Octave will run this example, and generate a plot:


np = 30;
p = rand(np, 3);
h = convhull(p);
nfaces = size(h, 1)
val = rand(nfaces + 1, 1);
patch('vertices', p, 'faces', h, 'facevertexcdata', val, 'facecolor',
'flat');
view(3);


where as matlab reports


Warning: Error creating or updating Patch
 Error in value of property  FaceVertexCData
 Number of colors must equal number of vertices or faces
