NAME
       grad -- gradient operator


SYNOPSIS
             form(const space V, const space& M, "grad");


DESCRIPTION
       Assembly  the  form  associated  to  the  gradient operator on a finite
       element space V:

                       /
                       |
             b(u, q) = | grad(u).q dx
                       |
                       / Omega

       The V space may be a either P1  or P2  finite element space, while  the
       M  space  may  be  P0   or  P1d   respectively.   See  also form(3) and
       space(3).


EXAMPLE
       The following piece of code build the divergence form associated to the
       P1 approximation:

               geo omega("square");
               space V(omega, "P1");
               space M(omega, "P0", "vector");
               form b(V, M, "grad");
