• Defined in File CSRMatrix.hpp

Class Documentation

template<class Precision, class IndexT>
class CSRMatrix

Manage memory of Compressed Sparse Row (CSR) sparse matrix. CSR format represents a matrix M by three (one-dimensional) arrays, that respectively contain nonzero values, row offsets, and column indices.

Template Parameters

• Precision – Floating-point precision type.

• IndexT – Integer type.

Public Functions

inline CSRMatrix(std::size_t num_rows, std::size_t nnz)

inline CSRMatrix(std::size_t num_rows, std::size_t nnz, IndexT *column_ptr, IndexT *csrOffsets_ptr, std::complex<Precision> *value_ptr)

CSRMatrix() = default

inline auto getColumns() -> std::vector<IndexT>&
