Details:

I tried demo("trisurf",1) and this works

The following script which I wrote produces an error message.  I don't think
it should...

vertices = [  1  1  1;
             -1 -1  1;
              1 -1 -1;
             -1  1 -1]
triangles = [ 1 2 3;
              2 1 4;
              3 2 4;
              4 1 3]

X = vertices(:, 1);
Y = vertices(:, 2);
Z = vertices(:, 3);

trisurf(triangles, X, Y, Z);

Here's the error message
