inv_mass -- invert of L2 scalar product
form(const space& V, const space& V, "inv_mass");
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).
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");
