Matlab cannot do regular meshes for non-regtancular regions.
However, one can manually do very coarse regular meshes for
these type domains. The difficulty is with the edge data e.
If this data does not correspond to the orientations given by
the PDEtool geometry files, refinement will not work. The
function drawedges() will display the order of the edges and
their segment numbers. However, this function does not tell
how the edges are oriented. However, just run the visualization,
and if the refinement does not work correctly, you know the
problem is with the orientatino of the edge. Remember to also
correct the last two rows of the matrix e when changing the
orientation. (See the documentation for initmesh for more info.)
