A Converting to LTEX Format A TEX is a program for typesetting mathematics, and L TEX is a macro package for TEX. The latex command converts Maple expressions to A A L TEX format. You can perform conversion to L TEX by using the latex command. Thus, you can use Maple to solve a problem, then convert the A A result to L TEX code that can be included in a L TEX document. Use the latex command in the following manner. latex( expr, "filename " ) • expr can be any mathematical expression. Maplespeciﬁc expressions, such as procedures, are not translatable • ﬁlename is optional, and speciﬁes that Maple writes the translated output to the ﬁle you speciﬁed. If you do not specify a ﬁlename, Maple writes the output to the default output stream (your session)
A • latex writes the L TEX code corresponding to the Maple expression expr to the ﬁle ﬁlename. If ﬁlename exists, latex overwrites it. If you 8.2 Writing Data to a File • 285 A omit ﬁlename, latex prints the L TEX code on the screen. You can A cut and paste from the output into your L TEX document. > latex( a/b ); {\frac {a}{b}} > latex( Limit( int(f(x), x=n..n), n=infinity ) ); \lim _{n\rightarrow \infty }\int _{n}^{n}\!f \left( x \right) {dx} The latex command:
A • Produces code suitable for L TEX math mode. However, it does not produce the command for entering and leaving math mode, and it does not attempt any line breaking or alignment. • Can translate most types of mathematical expressions, including integrals, limits, sums, products, and matrices. You can expand the capabilities of latex by deﬁning procedures with names of the form ‘latex/functionname ‘. Such a procedure formats calls to the function called functionname. You must produce the output of such formatting functions with the printf command. • Uses the writeto command to redirect the output when you specify a ﬁlename.
A • Does not generate the commands that L TEX requires to put the typesetting system into mathematics mode (for example, $...$). A The following example shows the generation of L TEX for an equation for an integral and its value. Note: Int, the inert form of int, prevents the evaluation of the lefthand side of the equation that Maple is formatting.
