HELP FOR: The TEX package.

CALLING SEQUENCE:

TEX[<function>](args)

<function>(args)

SYNOPSIS:

• This package provides an environment of functions that produce output which is suitable with a TeX processor. It knows how to format almost all the types defined in Maple, while it knows how to convert all standard internal Maple functions or objects such as integrals, limits, sums, products, and even arrays and tables.

• The mathematical format is taken, in general, from the command latex so that it is said to be as in the CRC handbook or the Handbook of Mathematical functions.

• Almost all the mathematical objects manipulated by ACE have a default corresponding function describing the output format. This is the case for symmetric function bases, noncommutative symmetric function bases, quasi-symmetric function bases, Schubert polynomials, ..., but it is still possible to modify these default formats.

• Whenever there is a conflict between a function name in TEX and another name used in the same session, use the long form TEX[<function>].

• The available functions are:

  Tex	TexCat	Texer	TexSeq
  TexStr

• It is possible to extend the abilities of TEX to format other objects by defining procedures named by: `TeX/UserdefinedFun/<name>` to define a format for the function whose name is <name>, `TeX/UserdefinedName/<name>` to define a format for the string whose name is <name><number>. `TeX/UserdefinedIndexed/<name>` to define a format for the indexed object whose name is <name>.

• When it encounters a call to <name>(...), the Tex function will call the procedure (if it exists) `TeX/UserdefinedFun/<name>`.

• When it encounters a name <name><number>, the Tex function will call the procedure (if it exists) `TeX/UserdefinedName/<name>` with the parameter <number>.

• When it encounters a name <name>[sequence], the Tex function will call the procedure (if it exists) `TeX/UserdefinedIndexed/<name>` with the the sequence of parameters sequence.

• Note that the output may include the commands to invoke the Tex math environment: this can be done by positionning some variables...

• For help with a particular function do either ?TEX[<function>] or ?TEX,<function> where <function> is one from the above list.

EXAMPLES:

> with(TEX):
> Tex(x^2 + y^2 = z^2);
x^{2}+y^{2}=z^{2}
> Tex(Int(1/(x^2+1), x) = int(1/(x^2+1), x),'TEX_MODE'='MATHS');
$\\int \\! {{1\\over x^{2}+1}}{dx}=\\arctan (x) $
> TexStr(`\\\\end`);
