mesh graphic object. Was: plotting numeric functions



Hello,

Do you mean how the matrix is projected on the (x,y)-plane? In that 
case, you can reverse de rows of the matrix as in

mesh (reverse(mat),  x0, y0, width, height) $



On the other hand, I'm planning to rename object 'mesh' and call it 
'elevation_grid', as in VRML. The idea is to call 'mesh' a new more 
general 3d graphic object. Some experimental examples and explanations here:

I can also change how the matrix is projected on the (x,y)-plane in a 
more convenient way, perhaps following standards in image analysis.

Also, I'm open to suggestions on the naming of the two functions.

Thanks.
