integer(kind(hipsparse_status_success)) function	hipsparsecsr2cscex2_ (handle, m, n, nnz, csrval, csrrowptr, csrcolind, cscval, csccolptr, cscrowind, valtype, copyvalues, idxbase, alg, buffer)

Detailed Description

Convert a sparse CSR matrix into a sparse CSC matrix.

hipsparseCsr2cscEx2 converts a CSR matrix into a CSC matrix. hipsparseCsr2cscEx2 can also be used to convert a CSC matrix into a CSR matrix. copyValues decides whether cscVal is being filled during conversion (HIPSPARSE_ACTION_NUMERIC) or not (HIPSPARSE_ACTION_SYMBOLIC).

Note

The resulting matrix can also be seen as the transpose of the input matrix.

This function is non-blocking and executed asynchronously with respect to the host. It can return before the actual computation has finished.

Parameters

[in]	handle	- handle to the hipSPARSE library context queue.
[in]	m	- number of rows of the sparse CSR matrix.
[in]	n	- number of columns of the sparse CSR matrix.
[in]	nnz	- number of non-zero entries of the sparse CSR matrix.
[in]	csrVal	- array of nnz elements of the sparse CSR matrix.
[in]	csrRowPtr	- array of m+1 elements that point to the start of every row of the sparse CSR matrix.
[in]	csrColInd	- array of nnz elements containing the column indices of the sparse CSR matrix.
[in]	cscVal	- array of nnz elements of the sparse CSC matrix.
[in]	cscColPtr	- array of n+1 elements that point to the start of every column of the sparse CSC matrix.
[in]	cscRowInd	- array of nnz elements containing the row indices of the sparse CSC matrix.
[in]	valType	- The data type of the values arrays csrVal and cscVal. Can be HIP_R_32F, HIP_R_64F, HIP_C_32F, or HIP_C_64F.
[in]	copyValues	- HIPSPARSE_ACTION_SYMBOLIC or HIPSPARSE_ACTION_NUMERIC.
[in]	idxBase	- HIPSPARSE_INDEX_BASE_ZERO or HIPSPARSE_INDEX_BASE_ONE.
[in]	alg	- HIPSPARSE_CSR2CSC_ALG_DEFAULT, HIPSPARSE_CSR2CSC_ALG1 or HIPSPARSE_CSR2CSC_ALG2.
[in]	buffer	- temporary storage buffer allocated by the user. The size is returned by hipsparseCsr2cscEx2_bufferSize().

Return values

HIPSPARSE_STATUS_SUCCESS	the operation completed successfully.
HIPSPARSE_STATUS_INVALID_VALUE	handle, m, n, nnz, csrRowPtr, csrColInd, or pBufferSizeInBytes pointer is invalid.
HIPSPARSE_STATUS_INTERNAL_ERROR	an internal error occurred.
