# How can PDE matrices be identified?

I need to include experimental results for lots of PDE (partial differential equation) matrices in my research work. How can I identify PDE matrices? For example, matrices in the UFL Sparse Matrix Collection.

• Indeed, you could just take the example programs of deal.II and in the solve() function of each of them just do something along the lines of system_matrix.print(std::cout);. May 12 '15 at 12:37
