Le forum de XCAS

Thanks, but I'm on linux. Supposedly the tool pdflatex convert tex files to pdf, but it returns some errors. Strange because GNU Texmacs works perfectly. Anyway, the generations of postcript works, not in landscape orientation but works.

Thanks for your reply. Searching in french documentation the menu option I'm talking is "Fisch -> Imprimer -> Pre-visualisation". With this option I don't see any tex file generated, just the .ps file.

In general configuration the Landscape option don't seems to work, the generated postscript is always vertical. If I understand correctly this option indicates the orientation of the generated postscript.

Ok, I installed FLTK 1.3 devel files (I had installed 2.0) and after this xcas compiles without problems. Thanks.

For plot(x**(1/3),x) I imagined that xcas took 3 as a real number, but I couldn't find a way to tell it to take it as...

Trying to draw a half sphere I came across an unexpected graphic with the following command: plotfunc(sqrt(9-x**2-y**2),[x,y]) I can plot a half-sphere with plotparam() command, but the graph from the previous command isn't what I expected. Is this a bug? Another question is with the following comma...

Thanks, it works now

Graphing several quadrics with the function quadric(), I found this problem with this entry: quadric(x^2-3y^2-2z-2,[x,y,z]) I get the message: Elliptical paraboloid with center [-0.0,-0.0,(x^2-3*y^2-2*z-2)/2.0] And the graph is just a plane. Is this a bug? Or am I doing something wrong? I'm using th...
