Mesh Data Partial Differential Equation Toolbox™ uses meshes with triangular elements for 2-D geometries and meshes with tetrahedral elements for 3-D geometries. As of MATLAB 7. The mesh and surf plotting functions display surfaces in three dimensions. You must provide an appropriate fixed mesh in xmesh. meshc(X,Y,Z) creates a mesh plot with a contour plot underneath.
