Member Function Documentation

void PetscIterativeSolver_Sparse::diagonalChanged ( int  idiag, int  extent  )

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.

Reimplemented from DoubleIterativeLinearSolver.

KSP PetscIterativeSolver_Sparse::ksp ( )

inline

int PetscIterativeSolver_Sparse::matrixChanged ( )

virtual

called if some elements of the matrix have changed. Triggers a refactorization of the matrix, if necessary.

Reimplemented from DoubleIterativeLinearSolver.

void PetscIterativeSolver_Sparse::solve ( OoqpVector &  x )

virtual

solves a linear system.

Parameters

x	on entry the right hand side of the system to be solved. On exit, the solution.

Implements DoubleIterativeLinearSolver.
