These macros +will give you some ideas on designing similar things for, e.g., +digital circuits. + +Trees are constructed with labels on the branches (default 0 and 1), and +with text (e.g., its name or value) on the nodes. The first parameter to +\verb|\branch| (0, 1, 2 or 3) determines the steepness of the branches. + +Example: +\small +\begin{verbatim} +\begin{picture}(100,100)(-50,10) +\unitlength=2mm +\branchlabels ABC % 012 is the default +\root(2,10) 0. % root at absolute coordinate (2,10) + % its (internally used) label is 0 + % the space before the 0 is obligatory +\branch2{16} 0:1,2. % node 0 (i.e., the root) has children 1 and 2 + % the text "1.00" is written above it + % space is optional, :,. are obligatory + \leaf{4}{$u_1$} 1. % node 1 is a leaf + % "0.45" written above, "$u_1$" to the right + \branch2{12} 2:3,7. % branch to node 3 goes up, and has label A + \tbranch2{9} 3:4,5,6. + \leaf{4}{$u_3$}4. % the symbols 0--7 can be replaced by anything + \leaf{3}{$u_4$}5. + \leaf{2}{$u_5$}6. + \leaf{3}{$u_2$} 7. +\end{picture} +\end{verbatim} +\normalsize +will typeset something like: +\begin{flushleft} +\begin{picture}(100,100)(-50,10) +\unitlength=2mm +\branchlabels ABC +\root(2,10) 0. +\branch2{16} 0:1,2. + \leaf{4}{$u_1$} 1. + \branch2{12} 2:3,7. + \tbranch2{9} 3:4,5,6. + \leaf{4}{$u_3$}4. + \leaf{3}{$u_4$}5. + \leaf{2}{$u_5$}6. + \leaf{3}{$u_2$} 7. +\end{picture} +\end{flushleft} +\end{document} |
