Functions
template<typename Matrix >
auto	Kaskade::makeDirectPreconditioner (Matrix &&A, DirectType directType=DirectType::MUMPS)
	Creates a direct solver for the given matrix. More...
template<int domainBlockSize, int rangeBlockSize, class Index >
auto	Kaskade::makeDirectPreconditioner (NumaBCRSMatrix< Dune::FieldMatrix< float, rangeBlockSize, domainBlockSize >, Index > &&A, DirectType directType=DirectType::MUMPS)
	Creates a direct solver for the given matrix. This specialization is for matrices containing floats (single precision) as scalar entries. Since the Kaskade interface for direct solvers only works for doubles, the matrix is copied into a new matrix with double as scalar entries. Since the coarse grid matrix often is much smaller, this hopefully means neglectable overhead. More...
