MATLAB!

made matlab post on ioct google groups with info on how to use it and beginning of signal processing.

minor reserch for paul regarding exporting plots to .obj file for 3d graphics

Saving a mesh

build a 3D plot and save this plot to 'parab.obj'.

[u,v]=meshgrid(-6:0.5:6,-6:0.5:6);
x=u; y=v; z=u.^2+v.^2;
mesh(x,y,z)
saveobjmesh('parab.obj',x,y,z)

This can then be imported into Abode Acrobat 3d. In this case a bit of scaling might be needed.
