Function Documentation
◆ bilu_decomposition()
template<class M >
void Dune::bilu_decomposition | ( | const M & | A, |
int | n, | ||
M & | ILU | ||
) |
ILU decomposition of order n Computes ILU decomposition of order n. The matrix ILU should be an empty matrix in row_wise creation mode. This allows the user to either specify the number of nonzero elements or to determine it automatically at run-time.
