Thread Subject: TRISURF not working

Dear All,
I've been trying to plot solution for my problem using TRISURF all to no avail.
I also know Trisurf is for {N x 3},so i tried QUADMESH (from the downloads) and still
doesn't work.

These are my data:
ELEM = [1 2 5 6
                3 4 7 8
                9 10 13 14
               11 12 15 16 ];
CORD = [ -1 0 0 1 -1 0 0 1 -1 0 0 1 -1 0 0 1;
                  -1 -1 -1 -1 0 0 0 0 0 0 0 0 1 1 1 1] ' ;
U = 0.0012*ones(16,1) ;

So, why should trisurf work on a quadrilateral mesh,
or a hexagonal mesh, or on anything other than a
triangular mesh? The tri in the name should be a major
hint here.

You say that you tried quadmesh (whatever that does)
but what did you try? Is quadmesh supposed to build
a mesh or plot it too?

You CAN use patch to plot this mesh. Did you try that?
