The default is 10pt. +% +% conference, journal, technote, peerreview, peerreviewca +% determines format mode - conference papers, journal papers, +% correspondence papers (technotes), or peer review papers. The user +% should also select 9pt when using technote. peerreview is like +% journal mode, but provides for a single-column "cover" title page for +% anonymous peer review. The paper title (without the author names) is +% repeated at the top of the page after the cover page. For peer review +% papers, the \IEEEpeerreviewmaketitle command must be executed (will +% automatically be ignored for non-peerreview modes) at the place the +% cover page is to end, usually just after the abstract (keywords are +% not normally used with peer review papers). peerreviewca is like +% peerreview, but allows the author names to be entered and formatted +% as with conference mode so that author affiliation and contact +% information can be easily seen on the cover page. +% The default is journal. +% +% draft, draftcls, draftclsnofoot, final +% determines if paper is formatted as a widely spaced draft (for +% handwritten editor comments) or as a properly typeset final version. +% draftcls restricts draft mode to the class file while all other LaTeX +% packages (i.e., \usepackage{graphicx}) will behave as final - allows +% for a draft paper with visible figures, etc. draftclsnofoot is like +% draftcls, but does not display the date and the word "DRAFT" at the foot +% of the pages. If using one of the draft modes, the user will probably +% also want to select onecolumn. +% The default is final. +% +% letterpaper, a4paper +% determines paper size: 8.5in X 11in or 210mm X 297mm. CHANGING THE PAPER +% SIZE WILL NOT ALTER THE TYPESETTING OF THE DOCUMENT - ONLY THE MARGINS +% WILL BE AFFECTED. In particular, documents using the a4paper option will +% have reduced side margins (A4 is narrower than US letter) and a longer +% bottom margin (A4 is longer than US letter). For both cases, the top +% margins will be the same and the text will be horizontally centered. +% For final submission to IEEE, authors should use US letter (8.5 X 11in) +% paper. Note that authors should ensure that all post-processing +% (ps, pdf, etc.) uses the same paper specificiation as the .tex document. +% Problems here are by far the number one reason for incorrect margins. +% IEEEtran will automatically set the default paper size under pdflatex +% (without requiring a change to pdftex.cfg), so this issue is more +% important to dvips users. Fix config.ps, config.pdf, or ~/.dvipsrc for +% dvips, or use the dvips -t papersize option instead as needed. See the +% testflow documentation +% http://www.ctan.org/tex-archive/macros/latex/contrib/supported/IEEEtran/testflow +% for more details on dvips paper size configuration. +% The default is letterpaper. +% +% oneside, twoside +% determines if layout follows single sided or two sided (duplex) +% printing. The only notable change is with the headings at the top of +% the pages. +% The default is oneside. +% +% onecolumn, twocolumn +% determines if text is organized into one or two columns per page. One +% column mode is usually used only with draft papers. +% The default is twocolumn. +% +% nofonttune +% turns off tuning of the font interword spacing. Maybe useful to those +% not using the standard Times fonts or for those who have already "tuned" +% their fonts. +% The default is to enable IEEEtran to tune font parameters. +% +% +%******* +% 09/2005 V1.6c (MDS) changes: +% +% 1) Changed endfigure/endfloat definitions so as not to cause problems with +% preview-LaTeX and other packages. Thanks to Stephan Heuel and David +% Kastrup for reporting this problem. +% +% +%******* +% 11/2002 V1.6b (MDS) changes: +% +% 1) Fixed problem with figure captions when using hyperref. Thanks to +% Leandro Barajas and Michael Bassetti for reporting this bug. +% +% 2) Provide a fake nabib command \NAT@parse so that hyperref will not +% interfere with the operation of cite.sty. However, as a result citation +% numbers will not be hyperlinked. Also, natbib will not be able to work +% with IEEEtran. However, this is perhaps the best solution until cite.sty +% and hyperref.sty are able to co-exist with each other. +% It easy enough to override the fake command via: +% \makeatletter +% \let\NAT@parse\undefined +% \makeatother +% +% 3) Revised font selection method so as not to have problems when used +% with setspace.sty. Thanks to Zhang Yan for reporting this bug. +% +% 4) Added \special to feed papersize to dvips. Thanks to Moritz Borgmann +% for suggesting this feature. +% +% 5) In addition to the IEEE IED lists, the original IED style list +% environments (as is done in article.cls) are now provided as +% LaTeXitemize, LaTeXenumerate, and LaTeXdescription. Also, users can +% now redefine \makelabel within IEEE IED list controls. There may be +% some use for this in specialized applications. Thanks to Eli Barzilay +% for suggesting this feature. +% +% 6) \table* now defaults to \footnotesize text like \table. +% +% 7) The draft modes now no longer force a pagebreak after the title. +% Thanks to Christian Peel for suggesting this change. +% +% 8) New draftclsnofoot mode is like draftcls, but does not display the +% date and the word "DRAFT" at the foot of the page. Thanks to +% Christian Peel for suggesting this feature. +% +% 9) New peerreview and peerreviewca modes with \IEEEpeerreviewmaketitle +% command allows for a "cover" titlepage for anonymous peer review. +% Except for the cover titlepage, peerreview is much like journal mode. +% peerreviewca is like peerreview, but allows the author names to be +% entered and formatted as under conference mode so that author +% affiliations and contact information can be easily seen on the cover +% page. Thanks to Eric Benedict for suggesting this feature. +% +% +%******* +% 7/2002 V1.6 (MDS) changes: +% +% 1) Added conference mode via conference option. Defaults to the traditional +% journal mode. i.e., \documentclass[conference]{IEEEtran} +% +% 2) Added support for A4 paper via new a4paper option. Pdflatex's paper size +% lengths are now automatically set to the proper paper size being used. +% +% 3) Revised margins again. Page text is now horizontally centered. +% Conference mode increases the top and bottom margins with the bottom +% margin being slightly larger. For A4 paper, the top margin and text +% typesetting will not change from those of US letter paper, but the side +% margins will be smaller and the bottom margin will be larger than that of +% US letter. All per IEEE specs. +% +% 4) Fixed footnote line spacing anomaly in draft mode. +% Thanks to Alberto Rodriguez for reporting this bug. +% +% Also, slightly revised footnote and \thanks note spacing. +% Set \interfootnotelinepenalty=10000 to prevent LaTeX +% from breaking footnotes across multiple pages or columns. +% +% 5) Fixed bug that caused overwritten photo areas and sometimes anomalous +% spacing when a new paragraph was started within a biography. Also, +% the presence of \par's, new lines or spaces at the beginning of +% abstract, keywords, biography, or biographynophoto will no longer +% affect the first word spacing. +% Thanks to Eric Durant for reporting this bug. +% +% The biography environment now does a better job in preventing +% a biography photo area from being broken across pages or columns. +% +% 6) Fixed whitespace between \cite entries bug. i.e., +% both \cite{einstein24, knuth84} and \cite{einstein24,knuth84} +% are now valid. \cite is now a robust command as it should be. +% IEEEtran now no longer defines the old non-standard \shortcite or +% \citename. +% +% The base IEEEtran.cls does not sort citation numbers or produce ranges +% for three or more consecutive numbers. However, V1.6 of IEEEtran.cls +% now pre-defines the following format control macros to facilitate easy +% use with Donald Arseneau's cite.sty package (tested with cite.sty V3.9): +% +% \def\citepunct{], [} +% \def\citedash{]--[} +% +% cite.sty is standard on most LaTeX sytems and can be obtained from +% www.ctan.org. Thanks to Donald Arseneau for creating cite.sty, providing +% the required format arguments to produce the IEEE style. and +% designing a cite interface capable of handling the IEEE citation +% style. +% +% Note: Historically, IEEE has wanted authors to "hardcode" symbolics. +% (i.e., replace all \cite{} with fixed [x]). However, it now seems that +% most electronic manuscript submissions to IEEE are in .pdf format, and +% as such, do not require the LaTeX document reference numbers to be hard +% coded. If an author is required to submit actual LaTeX files, I do +% recommend that the bibliography file (.bbl) be copied into the .tex +% document and the \bibliographystyle{} and \bibliography{} commands be +% commented out so that the .tex file does not depend on (potentially +% lengthy and/or confidential) external bibliography database files. +% +% 7) Adjusted some spacing parameters. The spacing above and below equations +% has been revised (to a typical IEEE value). \jot now has a decent value. +% The title text is now exactly 24pt. (On a related note, \fontsubfuzz has +% been increased to 0.9pt to prevent annoying font substitution warnings +% when using the Computer Modern fonts that use the 24.88pt size.) +% In V1.6, \small is now 8.5pt in 9pt docs because \footnotesize is 8pt. +% For 9pt docs, you should probably go ahead and use \footnotesize when you +% need text a little smaller than \normalsize. +% The interword spacing has been adjusted to be extremely close to that +% which IEEE uses. You can use a new class option, nofonttune, if you need +% to disable the adjusting of the interword spacing. This adjustment and +% an increase to \hyphenpenalty have greatly reduced the amount of +% hyphenation in a typical paper. +% The baselineskip for the normalsize fonts has been tweaked to reduce +% underfull vboxes on journal paper columns with only paragraphs. +% Conference mode does the same thing but by also tweaking the \textheight +% slightly off 9.25in (IEEE spec) to ensure an integer number of lines per +% page. Draft (also draftcls) mode has also been revised to reduce +% underfull vbox warnings. However, draft mode can still produce underfull +% vboxes (a direct result of the increase in line spacing and margins) if: +% A non-normalsize font occupies an entire column (abstract and index terms +% take up a whole column by themselves); or the beginning of a section +% occurs near the end of a column and cannot be squeezed into the bottom, +% etc. This is normal as draft mode's liberal spacings cannot guarantee +% perfect formatting. +% +% 8) New biographynophoto environment for biographies without photos. +% Usage: +% +% \begin{biographynophoto}{author name} +% biography text here +% \end{biographynophoto} +% +% 9) Fixed bug that produced multiple table of contents entries for papers +% with more than one biography. Also, biography now works better with +% hyperref. +% +%10) New \sublargesize font size command provides for 11pt text in a 10pt +% document. (Needed for things like author names.) For documents not +% using 10pt normal size text, \sublargesize is currently identical +% to \large. +% +%11) New \IEEEmembership command to provide correct font to indicate IEEE +% membership for journal papers. +% +%12) Fixed author name line overflow problem when in journal mode. This +% problem had been introduced in V1.5 in my rush to get \and to work for +% conferences. \and is unneeded (and invalid) in journal mode. For +% conference mode, \and will work as expected and features an optional +% spacing argument. i.e., \and[\hspace{5ex}] +% \and will default (recommended) to using \hfill which will result in +% equal spacing between author blocks. +% +%13) New \authorblockN, \authorblockA and \authorrefmark commands to +% facilitate easy formatting of author names, affiliations and cross +% reference symbols, respectively, when in conference mode. These +% three commands are to be used only for conference papers. +% In conference mode, \author text is placed within a modified tabular +% environment (somewhat like article.cls). So, within \author in conference +% mode, you should not try to enclose multiple \\ within an environment or +% command (other than the argument braces of \authorblockX{}). For example: +% +% \author{\authorblockN{{John Doe \\ Jane Doe}}} % WRONG! +% +% will generate an error. +% +% Note that font size/attribute changes will now persists across \\ within +% \author. (But, not across author blocks nor across \and.) +% However, with the new commands, there should be no need to alter any +% font attributes within \author. All text sizing and spacing within +% \author{} and the author block commands is per IEEE specs for both +% conference and journal modes. (In conference mode, the author names +% are only very slightly larger than the affiliations which are in normal +% size.) For specialized applications you can alter the justification of +% author lines by placing \hfill at the beginning or at the end of a line. +% The interline spacing within \author is determined by the font attributes +% that are in effect at the end of each line within author. +% +%14) Because the titles and author name blocks use different font sizes/styles +% from the main text, it was possible that two column papers with titles that +% span both columns (standard journal and conference papers, but not technotes) +% with certain numbers of lines for the title and authors' name/affiliations +% can cause underfull vbox problems (paragraphs with large spacings between +% them) in the second column of the main text on the title page - if there were +% no new sections, equations or figures in this column (they would provide some +% needed rubber spacing). The use of things like special paper notices and +% publisher ID marks also affected this issue. The problem could not happen +% in the first column because the first column has a rubber length around the +% heading of the first section. Furthermore, problems seldom occurred on pages +% after the first as the margins had been chosen not to cause it with the popular +% font sizes. Rubber lengths after the author names would not fix this problem. +% Auto-calculating a "good" spacing after the title is a tad difficult +% to do in LaTeX. However, I am pleased to report that V1.6 has this new +% capability - "dynamically determined title spacing". IEEEtran will now +% measure the height of all the title and author text in \maketitle +% and then calculate a rigid (non-rubber) spacer to follow that meets +% IEEE specs and also produces a \textheight on the title page that ensures +% an integer number of normalsized lines on the rest of the page. Single +% column papers, and two column papers with the title entirely in column +% one (technotes) do not need dynamic rigid spacing and therefore use +% standard rubber spacers. +% +% Note: This problem can still crop up if you use floats that span both +% columns (i.e., figure*). It has been a decade+ long limitation with LaTeX +% that the stretchable portion of \dbltextfloatsep is ignored. +% If you get a problem with underful vbox warnings and paragraphs that "are +% pulled apart" on page with a float that spans both columns, tweak the +% space between the figure and the main text a little: +% +% \vskip 5pt +% \end{figure*} +% +% If you can't find a value that fixes both columns, you are going to +% have to put a rubber spacer somewhere in one or both of the columns. +% +%15) Because of change #14 above, those of you using \pubid will, as of V1.6, +% have to place it *before* \maketitle in order for it have the intended +% affect. The dynamic spacer algorithm must see if you are using \pubid when +% \maketitle is called. \pubidadjcol works as before except that it now +% has additional logic to prevent it from doing anything if \pubid was never +% called. +% +%16) In some unusual, non-standard circumstances, an author may desire to +% alter the spacing after the title area or put some unusual text above +% the main text. For instance, to stop a bad break when a new section +% occurs right at the start of the second page. This is difficult to do +% when the title spans both columns of two column text since LaTeX treats +% such title text as a type of float. A new command, \IEEEaftertitletext{}, +% gives access to the end of that produced by \maketitle. The types of +% things that can go into \IEEEaftertitletext are the same as those into +% \twocolumn[] - no \par, but \\ are OK. There is no restriction on the +% range of spacings that can be used. +% i.e., \IEEEaftertitletext{\vspace{-100pt}} will push the main text well +% into the title and \IEEEaftertitletext{\vspace{100pt}} will push it far down +% the page. You will have complete control. If used, place +% \IEEEaftertitletext{} before \maketitle like \title and \author. IEEEtran's +% dynamic title spacing intentionally does not take into consideration the +% contents of \IEEEaftertitletext{} when determining the spacer after the title +% area (otherwise it would try to second guess you), so the user will have +% manually adjust the height of the contents in \IEEEaftertitletext{} if the +% problem discussed in #14 above should develop. A safe bet is to keep +% the height of contents of \IEEEaftertitletext{} to integer multiples of +% \baselineskip, i.e., \IEEEaftertitletext{\vspace{-1\baselineskip}} +% +% Because it can result in an IEEE nonstandard format, the use of +% \IEEEaftertitletext{} is discouraged. Possible uses include (1) the use of +% IEEEtran for non-IEEE work with different title spacing requirements, +% or (2) as an emergency manual override if a problem should develop in +% IEEEtran's automatic spacing algorithm. +% +%17) completely rewritten \PARstart to: +% a. no longer have problems when the user begins an environment +% within the paragraph that uses \PARstart. +% b. auto-detect and use the current font family +% c. revise handling of the space at the end of the first word so that +% interword glue will now work as normal. +% d. produce correctly aligned edges for the (two) indented lines. +% +% Because the current font family is now auto-detected, there is no +% longer any need for \CMPARstart - it is now the same as \PARstart. +% +%18) There is now a new "open box" Q.E.D. symbol (\QEDopen) as well as the +% original default (\QED) closed one (\QEDclosed). Some journals use +% the open form. To make \proof use the open form, just do: +% \renewcommand{\QED}{\QEDopen} +% +%19) Additional \typeout{} notices added to warn the user when unusual +% settings/commands are detected or as reminders to avoid common errors +% when in conference mode. +% +%20) IEEEtran now provides \abovecaptionskip and \belowcaptionskip skip +% registers because article class provides them and some packages +% may error if they are missing. However, IEEEtran only uses +% \abovecaptionskip for actual caption spacing. +% +%21) Fixed bug that prevented users from redefining the section headings +% to use arabic digits. Thanks to Richardt H. Wilkinson for reporting +% this bug. +% +%22) Code cleaned up to be more efficient with the use of TeX registers; +% removed some old LaTeX 2.09 code; revised option processing to +% LaTeX2e standard; eliminated unwanted "phantom" spaces in some +% environments. +% +%23) Added new \IEEEeqnarray, \IEEEeqnarraybox, \IEEEeqnarrayboxm and +% \IEEEeqnarrayboxt environments to provide superior alternatives to the +% standard LaTeX \eqnarray, \array and \tabular. Additional new support +% commands include \IEEEeqnarraydecl, \IEEEeqnarrayboxdecl, +% \IEEEeqnarraymathstyle, \IEEEeqnarraytextstyle, \yesnumber. \IEEEnonumber, +% \IEEEyesnumber, \IEEEyessubnumber, \IEEEeqnarraynumspace, \IEEEeqnarraymulticol, +% \IEEEeqnarrayomit, \IEEEeqnarraydefcol, \IEEEeqnarraydefcolsep, \IEEEeqnarrayseprow, +% \IEEEeqnarrayseprowcut, \IEEEeqnarrayrulerow, \IEEEeqnarraydblrulerowcut, +% \IEEEeqnarraystrutmode, \IEEEeqnarraystrutsize, \IEEEeqnarraystrutsizeadd, +% \IEEEvisiblestrutstrue, \IEEEvisiblestrutsfalse and \IEEEstrut. +% These are documented in the user's guide. +% +%24) V1.6 changed back to using () around theorem names (which are also now in italics) +% as this is what IEEE is using now. Thanks to Christian Peel for reporting this. +% Also, when section numbers are used as the first part of theorem numbers, display +% them in arabic, not Roman. +% +%25) New \IEEEtriggeratref{X} command allows a page break to be triggered just +% before the given reference number "X". This is most useful when balancing +% the columns on the last page and a \newpage between references is desired. +% \IEEEtriggercmd{X} allows a different command to be executed at trigger. +% +% +%******* +% 7/2001 V1.5 (MDS) changes: +% +% +% 1) Fixed \and within \author bug: (! Misplaced \crcr. \endtabular ->\crcr) +% Thanks to Rainer Dorsch for discovering and reporting that \and +% did not work. +% +% 2) Fixed the biography environment so that if a biography's text is shorter +% than the area allocated for the photo, a collision with the next +% biography does not occur. You can now put real graphics (using the +% graphicx package) into the biography photo box with a new optional +% argument of the biography command! For example: +% +% \begin{biography}[{\includegraphics[width=1in,height=1.25in,clip,keepaspectratio]{./tux.eps}}]{Linux Penguin} +% +% will use the specified graphic as the author's photo. The photo area is +% exactly 1in wide by 1.25in high - as is done in IEEE Transactions. Try +% to keep the same 4:5 aspect ratio if scanning/cropping your photos. +% Note the need for the extra set of enclosing braces around the +% \includegraphics. Without it, The LaTeX parser may get confused when it +% sees the \includegraphics's brackets within the biography's optional +% argument. Due to the length of the \includegraphics command, you may wish +% to define your own shorthand form of it. I have not done so with IEEEtran +% to prevent dependence on the graphicx package. If you do not use the +% optional argument, or leave it empty, a standard frame box with the +% words "Place Photo Here" will be used. If you want the space to remain +% completely empty, you can do: +% +% \begin{biography}[\mbox{}]{The Invisible Man} +% +% The interface to biography's optional argument is into a +% 1in X 1.25in minipage in which the argument text is centered both +% horizontally and vertically: +% +% \begin{minipage}[b][1.25in][c]{1in}% +% \centering +% #1% +% \end{minipage} +% +% Within the biography environment, \unitlength is set to 1in. +% With this in mind, you can even design your own custom frameboxes. +% For instance: +% +% \begin{biography}[\framebox(1,1.25){\parbox[][\height][c]{0.9in}{\centering PLACE\\ PHOTO\\ HERE}}]{Author Name} +% +% will yield the same type of result as the default photo box. +% +% Thanks to Herbert Voss for discovering the collision bug, suggesting the ability +% to handle graphics and providing some prototype code. +% +% +% +%******* +% 3/2001 V1.4 (MDS) changes: +% +% +% 1) New "draftcls" and "final" options have been added. +% Thanks to Dragan Cvetkovic for suggesting an option like draftcls. +% +% 2) Documentation changes to reflect the fact that this IEEEtran.cls +% is no longer beta test. +% +% 3) Slightly revised caption sizes. Figure and table captions are now +% in \footnotesize, not \small as before. +% +% 4) Allow user to control figure caption justification. IEEEtran.cls +% normally defaults to left justified as is done in Transactions. +% However, for conferences, you may wish to issue the command: +% \centerfigcaptionstrue +% in the preamble. Short (less than one line long) figure captions +% will then be centered. Multi-line figure captions will always be +% properly left justified. V1.6: This is already done for you when +% using the conference mode. +% +% +% +%******* +% 1/2001 V1.3 +% Michael Shell (MDS) made extensive changes and additions: +% +% +% BUGS FIXED (and many others too numerous to mention!): +% 1) Fixed improper alignment with itemized, enumerated and +% description lists. Added new controls to these three +% environments so that it is easy to get the alignment IEEE +% uses. Furthermore, the itemize, enumerate and description lists +% no longer force a new paragraph to begin at the end the list +% (\par). (Sometimes lists are used within paragraphs.) +% +% 2) JVH's fixes now allow things like $\mathbf{N}(0,P(0))$ +% to work properly without needing the extra braces: +% ${\mathbf{N}}(0,P(0))$. There is no longer any dependence +% on the "rawfonts" and "oldlfont" packages. Thanks Juergen! +% +% 3) Fixed underfull hbox errors and incorrect reference number +% alignment when the number of references in the bibliography +% exceeded 9 entries (which is almost every paper!). +% +% 4) Removed dependence on the LaTeX sizexx.clo files. +% Now, 9pt documents should work correctly even on systems that +% lack a size9.clo file. This is most often used in conjunction +% with the option "technote" for "correspondence" papers like those +% in IEEE Transactions on Information Theory. For virtually all +% other papers, 10pt is used and so it is the default. +% Some improper font sizes have been corrected. \footnotesize is +% now 8pt in 9pt docs, so footnotes in technotes should be the +% correct size now. +% +% 5) Added \interlinepenalty within the bibliography section to discourage +% LaTeX from breaking within a reference. IEEE almost never breaks within +% a reference and when they do it is usually in technotes +% (correspondence papers). You may get an underfull vbox warning in the +% bibliography indicating that the spacing just before the "REFERENCES" +% section is larger than normal, but the final result will be more like +% what IEEE will publish. See the comments in the BIBLIOGRAPHY section +% around line 2034 below if you want to change this behavior. +% +% 6) No longer "blows up" when you use \paragraph and have a table +% of contents. +% +% 7) Theorem environment changed, (but for V1.6, back to the old way, sigh). +% +% 8) Figure captions adjusted: IEEE left (not center) justifies +% figure captions (for journals) and does not indent figure caption text. +% +% 9) Adjusted some spacings in the table of contents(TOC))/list-of-figures/ +% list-of-tables so that section/table numbers will not so easily +% collide with the titles.
