Plot a triangular mesh in 3D. The variable tri is the triangular meshing of the points
(x,y)which is returned fromdelaunay. The variable z is value at the point(x,y). The output argument h is the graphic handle to the plot.
The following code
rand ('state', 10)
x = 3 - 6 * rand (1, 50);
y = 3 - 6 * rand (1, 50);
z = peaks (x, y);
tri = delaunay (x, y);
trimesh (tri, x, y, z);
Produces the following figure
