Summary description: Obtenir rapidement des tableaux de signes et de variations.
License type: lppl

Announcement text: 
----------------------------------------------------------------------
Permet de créer des tableaux de signes et de variations depuis latex 
en utilisant XCAS pour les calculs et MetaPOST pour les tableaux.
On rentre par exemple:
\begin{TV} TV([-10,+infinity],[-1,1],"g","t",x^2/(x^2-1),1,3) \end{TV} 
et on obtient le tableau de variation de x->x^2/(x^2-1).

.............

The tablor.sty package allows to create signs tables and
variations tables through latex using XCAS for  calculus and MetaPOST
to draw the tables.

For instance :

\begin{TV} TV([-10,+infinity],[-1,1],"g","t",x^2/(x^2-1),1,3) \end{TV} 

draws the variation table of function x->x^2/(x^2-1). 

It needs the metapost macro file tableauVariation.mp
You can download it there :

You can download XCAS there:
