%EVALEXPRP Evaluates an expression in the grid points.
%
%   [ VEVAL ] = EVALEXPRP( S_EXPR, PROB, SOLNUM, IND ) Evaluates the
%   expression S_EXPR in the points specified in PROB.GRID.P (in
%   global x/y/z-coordinates). PROB is a valid finite element problem
%   struct. Optional parameters are SOLNUM which indicates the chosen
%   solution, and IND for indexing which grid points are to be
%   evaluated for.
