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.
