class BlockMatrix¶

void set_block(std::size_t i, std::size_t j, std::shared_ptr<GenericMatrix> m)¶: Set block

std::shared_ptr<const GenericMatrix> get_block(std::size_t i, std::size_t j) const¶: Get block (const version)

std::shared_ptr<GenericMatrix> get_block(std::size_t i, std::size_t j)¶: Get block

std::size_t size(std::size_t dim) const¶: Return size of given dimension

void zero()¶: Set all entries to zero and keep any sparse structure

void apply(std::string mode)¶: Finalize assembly of tensor

std::string str(bool verbose) const¶: Return informal string representation (pretty-print)

void mult(const BlockVector &x, BlockVector &y, bool transposed = false) const¶: Matrix-vector product, y = Ax

std::shared_ptr<GenericMatrix> schur_approximation(bool symmetry = true) const¶: Create a crude explicit Schur approximation of S = D - C A^-1 B of (A B; C D) If symmetry != 0, then the caller promises that B = symmetry * transpose(C).
