Date: Jan­uary 15, 2008 1:54:05 PM CET
A new pack­age has been in­stalled on tug.ctan.org and should soon be at your fa­vorite mir­ror. Thank you, Jim Hef­feron Saint Michael's Col­lege ....................................................................... The fol­low­ing in­for­ma­tion was pro­vided by our fel­low con­trib­u­tor: 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: \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 : http://fred­eric.ma­zoit.free.fr/LaTeX_meta­post/tableauVari­a­tions/ You can down­load XCAS there: http://www-fourier.ujf-greno­ble.fr/%7Eparisse/giac.html You need to ac­ti­vate shell-es­cape. The non-french users need to com­ment out ev­ery « \usep­a­ck­age[up­right]{fourier} »
This pack­age is lo­cated at http://tug.ctan.org/tex-archive/macros/la­tex/con­trib/tablor . More in­for­ma­tion is at http://tug.ctan.org/pkg/tablor (if the pack­age is new it may take a day for that in­for­ma­tion to ap­pear). We are sup­ported by the TeX Users Group http://www.tug.org .

## tablor – Create ta­bles of signs and of vari­a­tions

The pack­age al­lows the user to use the com­puter al­ge­bra sys­tem XCAS to gen­er­ate ta­bles of signs and of vari­a­tions (the ac­tual plot­ting of the ta­bles uses the macro pack­age tableauVari­a­tions). Tables with for­bid­den re­gions may be de­vel­oped us­ing the pack­age.

A con­fig­u­ra­tion file per­mits some con­fig­u­ra­tion of the lan­guage to be used in the di­a­grams.

The tablor pack­age re­quires that shell es­cape be en­abled.
