UMFPACK based solver implementation.
An implementation of virtual class Solver using UMFPACK matrix solver library doing LU decomposition to solve linear matrix problems. This solver includes both linear and nonlinear solvers. Nonlinear solver based on Newton-Raphson iteration.

Destructor.
virtual void UMFPACKSolver::reset | ( | void | ) | [virtual] |
Reset solver.
This is a signal from the problem that the problem has changed and internal caches (if they exist) in the solver should be resetted.
Implements Solver.
