| SPOOLES is a library for solving sparse real and complex linear |
| systems of equations, written in the C language using object |
| oriented design. At present, there is the following functionality: |
| 1. Compute multiple minimum degree, generalized nested dissection |
| and multisection orderings of matrices with symmetric structure. |
| 2. Factor and solve square linear systems of equations with |
| symmetric structure, with or without pivoting for stability. |
| 3. Factor and solve overdetermined full rank systems of equations |
| using a multifrontal QR factorization. |
| 4. Solve square linear systems using a variety of Krylov iterative |
| methods. The preconditioner is a drop tolerance factorization, |
| with or without pivoting for stability. |
