type:$type_both

alias:TeXmath, math2tex

syntax:!texmath ``expr''

mean:Translate the mathematical expression ``expr'' into a TeX source. If the expression \

  is not a "machine-understandable mathematical expression", like products without *,\

  there is no garanty on the result \

  (at the moment and in the future !). See examples below.\

  Il might be useful to use ``!rawmath'' before applying ``!texmath''.<br>\

  The following transformations are performed:\

  <ul><li>\

   Transform computer matrix as [ 4,5;6,7] in latex matrix.\

   </li><li>\

   Transform A/B in {1 over B} A or { A over B} according to the priority of\

     the presume type of A and B (integer, numeric, variable, poly, transcend).\

   </li><li> transforms &lt;=, &lt;=&gt; =&gt;, -&gt; in tex/latex codes.\

   </li><li>\

   Transform a relation without a second member by adding 1.\

   </li><li>\

   Replace scientific notation 35E-05 by 10 power and add multiplication sign. Remove the + or 0 useless.\

  </li><li>\

   Remove the stars *.\

   </li><li>\

   Replace some names as greek letters by their equivalents.\

   </li><li>\

   interpret sum(), integrate, prod () (coming from maxima ) in tex/latex codes.\

</li></ul>
