Yes, there are functions like trimesh and trisurf in octave core and pdesurf and pdemesh in the package fpl which give them a pdetool compatible interface. The package fpl also contains functions to export triangular and tetrahedral mesh data to vtk format so that it can be visualized in paraview. > I tried using griddata to convert the triangular mesh data to square > grid, but results are not satisfactory.
