Question #158315 on DOLFIN changed: https://answers.launchpad.net/dolfin/+question/158315
Status: Answered => Open Nguyen Van Dang is still having a problem: Your advices are very helpful. Now I can get both stiffness matrix and mass matrix. Both of them are uBLASmatrix. Right? So, after having M, I call M=M.invert(); to took the inverse of matrix M. I got the error: 'class dolfin::Matrix' has no member named invert. Can you help me to solve this problem? I also want to access to all members of this matrix. It means m_{ij}. What will I do? Thank you very much for your time and your help!
