Member Function Documentation

convertCCS()

template<class F >

virtual void concepts::CRSConvertable< F >::convertCCS ( F *  a, int *  asub, int *  xa  ) const

pure virtual

Converts to Compressed Column Storage (CCS) format and writes values to field a, the row number asub and the index of the first value of each column xa. The fields have to be allocated with enough memory.

Implemented in concepts::SparseMatrix< F >.

convertCRS()

template<class F >

virtual void concepts::CRSConvertable< F >::convertCRS ( F *  a, int *  asub, int *  xa  ) const

pure virtual

Converts to Compressed Row Storage (CRS) format and writes values to field a, the column number asub and the index of the first value of each row xa. The fields have to be allocated with enough memory.

Implemented in concepts::SparseMatrix< F >.

convertIJK()

template<class F >

virtual void concepts::CRSConvertable< F >::convertIJK ( F *  a, int *  irn, int *  jcn  ) const

pure virtual

Convert to coordinate (COO) format and writes values to field a, the row indices to irn and the column indices to jcn. The fields have to be allocated with enough memory.

Implemented in concepts::SparseMatrix< F >.

used()

template<class F >

virtual uint concepts::CRSConvertable< F >::used ( ) const

pure virtual

Returns the number of used entries in the matrix.

Implemented in concepts::SparseMatrix< F >, concepts::SparseMatrix< FX >, concepts::SparseMatrix< Real >, and concepts::SubMatrixN< F >.
