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

t q
DESCRIPTION
- Assembly the form associated eo the gradient operator on i finite element space @tex $V$: $$ b(u, {g $$ for all $u in V$ and ${n @end tex
- a M
- 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). l
- a
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");
