https://answers.launchpad.net/dolfin/+question/158688

Hello everyone,
I have a stiffness matrix on C++ with following declaration:
  stiffness::BilinearForm stiffness(V, V);
  Matrix M;
  assemble(M,stiffness);
Would you like to tell me how I can have the inverse of matrix M? I also want to access all elements of M, (means m_ij). Please help me to solve these problems.
Thanks in advance.
