function h=pdegplot(g)
%PDEGPLOT Plot a PDE geometry specification.
%
%       PDEGPLOT(G) plots the boundary segments specified by G.
%       The internal boundaries are plotted.
%
%       H=PDEGPLOT(G) returns handles to the plotted axes objects.
%
%       G describes the geometry of the PDE problem. G can
%       either be a Decomposed Geometry Matrix or the name of Geometry
%       M-file. See either DECSG or PDEGEOM for details.
