Member Function Documentation

virtual void DoubleLinearSolver::diagonalChanged (  int    idiag, int    extent )  [pure virtual]

called if the diagonal elements of the matrix have changed. Triggers a refactorization of the matrix, if necessary. Parameters: idiag  index of the first diagonal element that changed extent  the number of diagonal element that changed. Implemented in DeSymIndefSolver, DeSymPSDSolver, Ma27SolverBase, and Ma57Solver.

virtual void DoubleLinearSolver::matrixChanged (    )  [pure virtual]

called if some elements of the matrix have changed. Triggers a refactorization of the matrix, if necessary. Implemented in DeSymIndefSolver, DeSymPSDSolver, Ma27SolverBase, and Ma57Solver.

virtual void DoubleLinearSolver::solve (  OoqpVector &    x )  [pure virtual]

solves a linear system. Parameters: x  on entry the right hand side of the system to be solved. On exit, the solution. Implemented in DeSymIndefSolver, DeSymPSDSolver, Ma27SolverBase, Ma27Solver, and Ma57Solver.
