Name of contribution: tablor Author's name: Guillaume Connan Location on CTAN: /macros/latex/contrib/tablor 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: egin{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 :
egin{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:

You need to activate shell-escape.
