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.)
