NAME

       inv_mass -- invert of L2 scalar product

SYNOPSIS

               form(const space& V, const space& V, "inv_mass");

DESCRIPTION

       Assembly  the  invert of the matrix associated to the L2 scalar product
       of the finite element space V:

                        /
                        |
               m(u,v) = | u v dx
                        |
                        / Omega

       The V space may be either a P0  or  P1d  discontinuous  finite  element
       spaces see form(3).

EXAMPLE

       The  following  piece  of  code  build  the  invert  of the mass matrix
       associated to the P1d  approximation:

               geo omega_h ("square");
               space Vh (omega_h , "P1d");
               form im (Vh, Vh, "inv_mass");
