* \brief Incomplete LU factorization with 0 fill-ins and no pivoting using the BSR storage
|
|
* format.
|
|
*
|
|
* \details
|
|
* \p hipsparseXbsrilu02 computes the incomplete LU factorization with 0 fill-ins and no
|
|
* pivoting of a sparse \f$mb \times mb\f$ BSR matrix \f$A\f$, such that
|
|
* \f[
|
|
* A \approx LU
|
|
* \f]
|
|
*
|
|
* Computing the above incomplete LU factorization requires three steps to complete. First,
|
|
* the user determines the size of the required temporary storage buffer by calling
|
|
* \ref hipsparseSbsrilu02_bufferSize "hipsparseXbsrilu02_bufferSize()". After this buffer size
|
|
* has been determined, the user allocates the buffer and passes it to
|
|
* \ref hipsparseSbsrilu02_analysis "hipsparseXbsrilu02_analysis()". This will perform analysis on
|
|
* the sparsity pattern of the matrix. Finally, the user calls \p hipsparseXbsrilu02 to perform the
|
|
* actual factorization. The calculation of the buffer size and the analysis of the sparse matrix
|
|
* only need to be performed once for a given sparsity pattern, while the factorization can be
|
|
* repeatedly applied to multiple matrices having the same sparsity pattern. After all calls to
|
|
* \ref hipsparseSbsrilu02 "hipsparseXbsrilu02()" are complete, the temporary buffer can be deallocated.
|
|
*
|
|
* \p hipsparseXbsrilu02 reports the first zero pivot (either numerical or structural zero).
|
|
* The zero pivot status can be obtained by calling \ref hipsparseXbsrilu02_zeroPivot().
|
|
*
|
|
* \note
