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.
