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
idiagindex of the first diagonal element that changed
extentthe number of diagonal element that changed.
