KOKKOS_INLINE_FUNCTION T & operator() (size_t i, size_t j) const

Access method to A(i,j) returns a dummy value of 0 if value is not allocated.

Parameters

i – row
j – column

Returns

KOKKOS_INLINE_FUNCTION&

KOKKOS_INLINE_FUNCTION T & value (size_t i, size_t j) const

Same functionality as operator. Included for compatibility with other matar types.

Parameters

i –
j –

Returns

KOKKOS_INLINE_FUNCTION&

KOKKOS_INLINE_FUNCTION CSRArrayKokkos & operator= (const CSRArrayKokkos &temp)

Copy operator.

Parameters: temp –

KOKKOS_INLINE_FUNCTION T * pointer () const: Pointer to start of array_ data.

KOKKOS_INLINE_FUNCTION size_t * get_starts () const: Get the beginning of the start_index_ array.

KOKKOS_INLINE_FUNCTION size_t dim2 () const

Number of columns.

Returns: KOKKOS_INLINE_FUNCTION

KOKKOS_INLINE_FUNCTION size_t dim1 () const

Number of rows.

Returns: KOKKOS_INLINE_FUNCTION

KOKKOS_INLINE_FUNCTION T * begin (size_t i)

iterator notation to access the non zero elements of row i. Returns pointer to first element in row i

Parameters: i – row
Returns: KOKKOS_INLINE_FUNCTION*

KOKKOS_INLINE_FUNCTION T * end (size_t i)

Iteator notation to access the non zero elements of row i. Returns pointer first element of the next row.

Parameters: i –
Returns: KOKKOS_INLINE_FUNCTION*

KOKKOS_INLINE_FUNCTION size_t stride (size_t i) const

Get the size of row i. Same functionality as nnz(i) but included for compatiblity.

Parameters: i –
Returns: KOKKOS_INLINE_FUNCTION
