Bonjour,
I'am a french mathematic teacher and i need to represent surface and
level lines with color beetween level lines ;
for example, z=2x^2-x+y^2 (x in 0,10 ; y in 0,10) and one color from
z=0 to z=25, another color from 25 to 50,....
Is it possible with maxima (i think it is not with gnuplot)
Merci :-)
Jean-Pierre
