I do not have write access to official repo to add this myself but may spend a few hours to get paremeters and comments right. I could also provide two examples, one then interpolating on scattered data and one then importing mesh from Fenics hdf5 file. Importing solutions saved in hdf5 file format, .h5 filer are simple with load command but indexes start at zero for triangulation so +1 need to be added. Mesh could be plotted with triplot(...) function and a scalar solution with plot3(...) function.

For plotting you could consider the fpl package that offers functions "pdemesh" and "pdeplot" compatible with matlab's pdetool and *vtk* methods to export in formats viewable with paraview.

And, if you are working with triangular meshes a lot, the msh package offers a few functions to create and manage meshes, including creating and importing meshes from gmsh.
