EX_POISSON2 2D Poisson equation example on a circle.

[ FEA, OUT ] = EX_POISSON2( VARARGIN ) Poisson equation on a circle with source term 1 and exact solution u=(1-r^2)/4. Accepts the following property/value pairs.

Input       Value/{Default}        Description
radi        scalar {1}             Radius of circle
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)
igrid       scalar -1/{0}          Cell type (0>=triangles, 0<quadrilaterals)
iplot       scalar 0/{1}           Plot solution (=1)
Output      Value/(Size)           Description
fea         struct                 Problem definition struct
out         struct                 Output stuct
