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");
