EX_POISSON3 2D Poisson equation example on a unit square.

[ FEA, OUT ] = EX_POISSON3( VARARGIN ) Poisson equation on a [0..1]^2 unit square.

Input       Value/{Default}        Description
igrid       scalar 1/{0}           Cell type (0=quadrilaterals, 1=triangles)
hmax        scalar {0.1}           Max grid cell size
sfun        string {sflag1}        Shape function
iphys       scalar 0/{1}           Use physics mode to define problem    (=1)
                                   or directly define fea.eqn/bdr fields (=0)
iplot       scalar 0/{1}           Plot solution (=1)
