|
* \brief Convert a sparse CSR matrix into a sparse CSC matrix.
|
|
*
|
|
* \details
|
|
* \p hipsparseXcsr2csc converts a CSR matrix into a CSC matrix. \p hipsparseXcsr2csc
|
|
* can also be used to convert a CSC matrix into a CSR matrix. \p copyValues decides
|
|
* whether \p cscSortedVal is being filled during conversion (\ref HIPSPARSE_ACTION_NUMERIC)
|
|
* or not (\ref HIPSPARSE_ACTION_SYMBOLIC).
|
|
*
|
|
* For example given the matrix:
|
|
* \f[
|
|
* \begin{bmatrix}
|
|
* 1 & 0 & 0 & 2 \\
|
|
* 3 & 4 & 0 & 0 \\
|
|
* 5 & 0 & 6 & 7
|
|
* \end{bmatrix}
|
|
* \f]
|
|
*
|
|
* Represented using the sparse CSR format as:
|
|
* \f[
|
|
* \begin{align}
|
|
* \text{csrSortedRowPtr} &= \begin{bmatrix} 0 & 2 & 4 & 7 \end{bmatrix} \\
|
|
* \text{csrSortedColInd} &= \begin{bmatrix} 0 & 3 & 0 & 1 & 0 & 2 & 3 \end{bmatrix} \\
|
|
* \text{csrSortedVal} &= \begin{bmatrix} 1 & 2 & 3 & 4 & 5 & 6 & 7 \end{bmatrix}
|
|
* \end{align}
|
|
* \f]
|
|
*
|
|
* this function converts it to the sparse CSC format:
|
|
* \f[
|
|
* \begin{align}
|
|
* \text{cscSortedRowInd} &= \begin{bmatrix} 0 & 1 & 2 & 1 & 2 & 0 & 2 \end{bmatrix} \\
|
|
* \text{cscSortedColPtr} &= \begin{bmatrix} 0 & 3 & 4 & 5 & 7 \end{bmatrix} \\
|
|
* \text{cscSortedVal} &= \begin{bmatrix} 1 & 3 & 5 & 4 & 6 & 2 & 7 \end{bmatrix}
|
|
* \end{align}
|
|
* \f]
|
|
*
|
|
* The CSC arrays \p cscSortedRowInd, \p cscSortedColPtr, and \p cscSortedVal must be allocated by the
|
|
* user prior to calling \p hipsparseXcsr2csc().
|
|
*
|
|
* \note
|
|
* The resulting matrix can also be seen as the transpose of the input matrix.
|
|
*
|
|
* \note
|
|
* This function is non-blocking and executed asynchronously with respect to the host.
|
|
* It can return before the actual computation has finished.
|
|
*
|
|
* \deprecated
|
|
* This function is deprecated when using the CUDA backend (CUDA 10.0+) and will be
|
|
* removed in CUDA 11.0. This deprecation does not apply to the ROCm backend.
