Every author has his or her own +% notation, making it very difficult to comprehend what is going on +% in complex multi reference axes environments. +% +% This package is based on the notation of \Hass\cite{Hass93a,Hass93b}. +% It was developed and refined by Dr.~\Hass{} over many years of +% teaching engineering, and as stated by him\cite{Hass93a}: +% +% \begin{quote} +% \slshape``It is designed particulary to distinguish between +% vectors and tensors and their representation as vectors and matrices +% in different coordinate systems. The main purpose of this notation +% is that it can be used in the teaching situation, therefore, it +% conveys all the information explicitly in the symbols, and it can be +% used in handwriting.'' +% \end{quote} +% \noindent \Hass\cite{Hass93a} identifies the following list of +% requirements for a good notation for tensor quantities and +% operations, to which his notation conforms. A notation must: +% \begin{itemize} +% \item be easily written by hand; +% \item distinguish between vector and scalar quantities; +% \item distinguish between (second order) tensors and vectors; +% \item distinguish between physical vectors and their +% representation by vector arrays, and between physical +% (second order) tensors and their representation by matrices; +% \item distinguish between row and column vectors; +% \item use the same symbol as name for the same vector or tensor in +% either its physical sense or its representation by a vector +% array or matrix in different coordinate axes; +% \item distinguish between matrix/vector representation of the same +% vector/tensor in different coordinate axes; +% \item be equally valid in orthonormal and skew coordinate +% axes; +% \item indicate all intended operations uniquely; +% \item be equally valid in all dimensions; +% \item be equally valid for algebraic vector/matrix algebra +% which has no connection to any metric space; +% \item be applicable to differentials; +% \item allow for defaults to avoid repetitive elaborate symbols, i.e., +% not all the symbols need to be written down explicitly if it is +% clear from the context. +% \item It must be well documented (own addition). +% \end{itemize} +% +% \noindent The \MT\ package was developed to typeset the \Hass{} matrix +% tensor symbols in a consistent manner. +% +% An appeal is made to +% the engineering and scientific community to adopt +% this notation, because of its consistency +% and ease of use. +% +% +% \section{Usage of \MT\ package} +% +% The \MT\ package is loaded in the document preamble with: +% \begin{quote} +% \begin{tabbing}^^A +% \hskip14pc\=\kill^^A +% $~~~\vdots$\\ +% \cmd{\usepackage}\oarg{options}|{mattens}| \>|% amsmath loaded internally|\\ +% $~~~\vdots$\\ +% \cmd{\usepackage}\marg{font packages} \>|%|\\ +% \cmd{\DeclareSymbolFont}... \>|% All the font changes|\\ +% \cmd{\SetSymbolFont}... \>|%|\\ +% \cmd{\DeclareSymbolFontAlphabet}... \>|%|\\ +% $~~~\vdots$\\ +% \cmd{\usepackage}|{bm} %\boldsymbol redirected to call \bm|\\ +% $~~~\vdots$ +% \end{tabbing} +% \end{quote} +% +% \noindent When \MT\ is loaded, the \pkg{amsmath} package is loaded +% automatically, because it is needed for the redefined +% \cmd{\overrightarrow} and \cmd{\underrightarrow} commands, +% as well as the \cmd{\boldsymbol} command. It +% must be loaded before any font packages +% that redefine some of the \pkg{amsmath} symbols or commands. +% +% On the other hand, the preferred method for obtaining bold +% italic math symbols is the \cmd{\bm} command of the +% \pkg{bm} package.\footnote{In the \pkg{amsmath} documentation, +% \AmS{} recommends the \cmd{\bm} command of the \pkg{bm} package +% instead of the \cmd{\boldsymbol} command for bold italic math +% symbols. The \cmd{\boldsymbol} puts its contents in a box, +% \cmd{\mbox\{}\cmd{\boldmath\$}\meta{contents}\texttt{\$\}}, +% while \cmd{\bm} is a font changing command that uses the appropriate +% bold math font.} +% The \pkg{bm} package must be loaded after all the font packages +% in order for it to recognize the bold math versions. +% The \pkg{bm} package reroutes the \cmd{\boldsymbol} command to point +% to \cmd{\bm}. If \cmd{\boldsymbol} is called after +% the \pkg{bm} package is loaded, it is equivalent to +% \cmd{\bm}. +% If the \pkg{bm} package is not loaded, \MT\ defaults to +% the \cmd{\boldsymbol} command. +% +% The \MT\ package by default sets bold italics symbols. This +% choice stems from the ISO standards for typesetting of vectors +% and tensors. The formatting of symbols then indicates the fact +% that it is a vector/tensor and the lines, arrows and sub- and +% superscripts indicate the specific type and reference axes. +% +% The following options are recognized by \MT: +% +% \begin{description} +% \item[\normalfont\opt{noformat}:~~ ] No symbol formatting is performed, +% otherwise symbols are set by default in bold italics with the +% \cmd{\boldsymbol} or \cmd{\bm} command. +% +% It is important to note that the \Hass{} requirement of easily +% written by hand is not fulfilled if the symbols are formatted +% by anything else than normal math fonts. +% +% \item[\normalfont\opt{mathstrut}: ~~] A mathstrut is inserted +% with the symbol to force all the lines and arrows to the same +% height and depth. The default is no mathstrut. +% \end{description} +% +% \clearpage +% \section{List of \MT\ commands} +% +% \begin{table}[htbp] +% \caption{List of Matrix Tensor typing commands} \label{tab:1} +% \small +% \renewcommand{\footnoterule}{} +% \begin{tabular}{@{}ll>{\itshape}r@{}>{\itshape}c@{}>{\itshape}lc@{}} +% \sphline +% \bfseries Type & +% \bfseries Command & +% \multicolumn{3}{c}{ +% \bfseries Description} & +% \bfseries Output\\ +% \sphline +% Physical column vector& +% \cmd{\aS}\oarg{accent}\marg{Symbol}\SpecialUsageIndex{aS} & +% arrow--&Symbol& & +% \aS{x} \\[1.0ex] +% +% Physical row vector & +% \cmd{\Sa}\oarg{accent}\marg{Symbol}\SpecialUsageIndex{Sa} & +% &Symbol&--arrow& +% \Sa{x} \\[1.0ex] +% +% Column vector & +% \cmd{\bS}\oarg{accent}\marg{Symbol}\SpecialUsageIndex{bS} & +% bar--&Symbol& & +% \bS{x} \\[1.0ex] +% +% Row vector & +% \cmd{\Sb}\oarg{accent}\marg{Symbol}\SpecialUsageIndex{Sb} & +% &Symbol&--bar & +% \Sb{x} \\[1.0ex] +% +% Physical tensor & +% \cmd{\aSa}\oarg{accent}\marg{Symbol}\SpecialUsageIndex{aSa}& +% arrow--&Symbol&--arrow& +% \aSa{E}\\[1.0ex] +% +% Tensor (mixed base) & +% \cmd{\aSb}\oarg{accent}\marg{Symbol}\SpecialUsageIndex{aSb}& +% arrow--&Symbol&--bar & +% \aSb{E}\\[1.0ex] +% +% Tensor (mixed base) & +% \cmd{\bSa}\oarg{accent}\marg{Symbol}\SpecialUsageIndex{bSa}& +% bar--&Symbol&--arrow& +% \bSa{E}\\[1.0ex] +% +% Tensor & +% \cmd{\bSb}\oarg{accent}\marg{Symbol}\SpecialUsageIndex{bSb}& +% bar--&Symbol&--bar & +% \bSb{E}\\[1.0ex] +% +% Cross-product tensor$^\dag$ +% & +% \cmd{\aCSa}\oarg{accent}\marg{Symbol}\SpecialUsageIndex{aCSa}& +% arrow--C&Symbol&--arrow& +% \aCSa{w} \\[1.0ex] +% +% Cross-product tensor & +% \cmd{\bCSb}\oarg{accent}\marg{Symbol}\SpecialUsageIndex{bCSb}& +% bar--C&Symbol&--bar & +% \bCSb{w} \\[1.0ex] +% +% \sphline +% +% \multicolumn{5}{@{}l}{\footnotesize$^\dag$~ +% It is defined as the tensor +% \bCSb{a}\ associated with the vector \bS{a}, where +% $\bS{a}\times\bS{c}=\bCSb{a}\cdot\bS{c}$} +% \end{tabular} +% \end{table} +% +% \subsection{General syntax} +% +% The general syntax of the \MT\ commands is +%{\newcommand*\m{\raisebox{.1ex}{$\scriptscriptstyle\square$}}^^A +% \begin{Decl} +% |\|\m|S|\m\,| |\oarg{accent}\marg{Symbol} ~~ +% |\|\m|CS|\m\,| |\oarg{accent}\marg{Symbol}\\[1ex] +% |\|\m|S|\m\,|*|\oarg{accent}\marg{Symbol}~~~ +% |\|\m|CS|\m\,|*|\oarg{accent}\marg{Symbol} +% \end{Decl}} +% +% \noindent with command names \cmd{\bS}, \cmd{\aS}, \cmd{\aSa}, \cmd{\aSb}, etc. +% See table\:\ref{tab:1} for a full list of all the commands.

When +% the \cmd{\overline} or \cmd{\overrightarrow} commands are used together +% with math accents, the problems begin\footnote{If you are using +% Equation Editor or MathType inside word processors in the Windows environment, +% you end up with the same problems and have to fiddle \myemph{every} +% sub- and superscript individually. A browse through the accompanying +% sample document, \pkg{mtsample.tex}, will show that this can amount to +% hundreds of little equations. I challenge anyone to rewrite that +% document with one of the popular wordprocessors and still be sane +% afterwards :-)}: +% +% \begin{itemize} +% +% \item +% For an \cmd{\overline}, $\overline{f}^a_b$, the superscript moves up +% to the height of the overline, which is fine for vector notation, +% but the subscript kerning is lost, because the symbol is set +% inside a box with italic correction added (App. G of the +% \TeX{}book). If the subscript is added inside the \cmd{\overline} +% construct, $\overline{f_b}^a$, the overline is stretched, which is +% acceptable only when the subscript is part of the symbol itself. +% The subscript kerning can be corrected by attaching the subscript +% to the symbol and the superscript to the overline and then overtyping +% (\cmd{\rlap} or \cmd{\llap}) them while using a phantom symbol (without +% subscript) for the overline, +% \begin{sample} +% |\leavevmode\rlap{$\overline{\phantom{f}}^a$}%|\\ +% | {$f^{}_b$}| +% \end{sample} +% which gives \leavevmode\rlap{$\overline{\phantom{f}}^a$}{$f^{}_b$}. +% +% The \cmd{\leavevmode} command is nessesary to prevent the symbol +% being spread over two lines when it is the first token in a new +% paragraph (\TeX{} in vertical mode). +% +% Care must be taken with the sequence in which the two parts +% overlap when the one is wider than the other, +% \leavevmode\rlap{$\overline{\phantom{f}}^{abcde}$}{$f^{}_a$}, +% because the superscript will then run into the following text. +% +% \item +% If a math accent is added to the overline, \usebox{\AccentBox}, +% the superscript goes to the level of the accent (except if the +% \pkg{accents}\ package is loaded). This can be remedied by +% controlling the height of the accented overline construction with +% a \cmd{\vphantom} commands as a strut, +% ^^A +% \begin{sample} +%|\leavevmode\rlap%|\\ +%| {$\dot{\overline{\phantom{f}}}{\vphantom{\overline{f}}}^a$}%|\\ +%| {$f^{}_b$}| +% \end{sample} +% which gives +% \rlap^^A +% {$\dot{\overline{\phantom{f}}}{\vphantom{\overline{f}}}^a$}^^A +% {$f^{}_b$}. +% +% \item +% For an |\overrightarrow| in vector notation, +% ($\overrightarrow{i}_a$, ~$\overrightarrow{iiii}_a\,$), the +% construction of the stretchable arrow results in an arrow wider +% than most symbols, with the symbol centred below it. +% The subscript ended up far removed from the symbol. +% For multiple symbols, the arrow width is equal to the box containing +% the letters, resulting in better-looking subscripts +% (but still without the subscript kerning). +% The previous procedure can be used to correct the +% subscript kerning, except that additional white space must be +% inserted before the symbol to centre it beneath the arrow. +% +% \begin{sample} +% |\newlength{\Wspace}\settowidth{\Wspace}{$\overrightarrow{i}$}|\\ +% |\newlength{\SymWdth}\settowidth{\SymWdth}{$i$}|\\ +% |\addtolength{\Wspace}{-\SymWdth} |\\ +% |\leavevmode\rlap% |\\ +% | {$\dot{\overrightarrow{\phantom{i}}}$}% |\\ +% | {\hspace*{.5\Wspace}$i^{}_b$} |\\ +% \end{sample} +% \newlength{\Wspace}\settowidth{\Wspace}{$\overrightarrow{i}$} +% \newlength{\SymWdth}\settowidth{\SymWdth}{$i$} +% \addtolength{\Wspace}{-\SymWdth} +% which gives \rlap{$\dot{\overrightarrow{\phantom{i}}}$}{\hspace*{.5\Wspace}$i^{}_b$}. +% +% The commands can be optimized by using saveboxes, \myemph{but} +% the symbols will not scale correctly when used as sub- or +% superscripts or in the \cmd{\tfrac} macro. A solution is to nest +% the commands inside a \cmd{\mathpalette} environment, but be warned, +% this is very expensive! +% The commands \cmd{\phantom}, \cmd{\smash}, \cmd{\overrightarrow} +% (in \pkg{amsmath}) are already inside \cmd{\mathpalette} macros, and +% \TeX{} calls the arguments of a \cmd{\mathpalette} macro four times +% before deciding on the dimensions. +% +% \item +% The shape of the arrow tip of the |\overrightarrow| command was +% probably not designed for this type of application and is much too +% broad in the final CM font version. This broad arrow shape is +% incidentally one of last changes by Prof.~Knuth to the CM font symbols. +% The PostScript version of the CM fonts typesets the arrow much +% better, but it is highly likely that it is still the old outdated +% version of the symbol. +% +% \item +% The subscript heights differ for the cases with and without +% superscripts, $x_b,\; x_b^a$. This is not very satisfactory for a +% consistent matrix-tensor notation, but it can be remedied by +% inserting a dummy superscript, |$x^{}_b$|, which then gives +% $x^{}_b$, $x_b^a$. +% +% \end{itemize} +% +% The \MT\ package was developed to overcome (some of) the above-mentioned +% problems and to typeset the \Hass{} matrix tensor symbols in a +% consistent manner. +% +% +% \subsection{To do's} +% +% \begin{itemize} +% \item +% The vertical spacing between the symbols and the lines and arrows +% differs, \aSb{E}, \bSa{E}. This problem cannot be fixed easily +% and would need some additional struts or even a rewriting of the +% arrows and lines commands. +% +% \item +% For the purists: The ends of the |\overrightarrow| are rounded +% (ligature of symbols), while the ends of the |\overline| are squared +% (\TeX{} line drawing). +% +% \item +% \MT\ does not yet work with the \pkg{xspace} package. +% \end{itemize} +% +% \section{Bugs, etc.} +% +% I am sure there is much room for improvement, because +% I am a \TeX{}natic and not a \TeX{}pert and to quote +% Knuth from the \TeX{}book: +% \begin{quote} +% {\slshape\small Always remember, however, that there's usually +% a simpler and better way to do something than the first way that +% pops into your head.
