Direct Matrix access

std::vector<std::vector<ScalarType>> danceq::internal::SparseMatrix::get_dense(void) const

Returns the dense matrix using std::vector.

Returns:

Dense matrix

ScalarType danceq::internal::SparseMatrix::get_element(const uint64_t row, const uint64_t col) const

Returns element at a certain position.

If the element does not exists zero is returned.

Parameters:

  • row – Row

  • col – Column

Returns:

Element

bool danceq::internal::SparseMatrix::is_element(const uint64_t row, const uint64_t col) const

Checks if element at a certain position.

Parameters:

  • row – Row

  • col – Column

Returns:

true if element exists false if it does not exists

std::vector<ScalarType> danceq::internal::SparseMatrix::get_diag(void) const

Returns full diagonal of matrix.

Returns:

Diagonal of size dim
