Re: plotting in 3D

[Etienne Grossmann]

  Hello,

From: address@hidden
#  Hi
#
#  I don't understand how to plot in 3d a matrix (30 x 3). I read
#  sombrero.m but in my case the mesh is partial, and the "gset
#  parametrics" is ununderstandable.
#
#  any help ?

  What about :

octave:361> [x, y] = meshgrid (linspace (-10,10,30),linspace (-10,10,30));
octave:362> z = sin (x) + y.^2/100;
octave:363> mesh (x, y, z)

  I have written a 'vmesh (x,y,z)' function that launches a VRML
browser and lets you examine your surface. No axes or tics, though;
also, you need to have the browser installed.


   Cheers,


   Etienne
