* \brief Incomplete LU factorization with 0 fill-ins and no pivoting using the BSR storage
|
|
* format
|
|
*
|
|
* \details
|
|
* \p rocsparse_bsrilu0 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,
|
|
* determine the size of the required temporary storage buffer by calling
|
|
* \ref rocsparse_sbsrilu0_buffer_size "rocsparse_Xbsrilu0_buffer_size()". After this buffer size
|
|
* has been determined, allocate the buffer and pass it to
|
|
* \ref rocsparse_sbsrilu0_analysis "rocsparse_Xbsrilu0_analysis()". This will perform analysis on
|
|
* the sparsity pattern of the matrix. Finally, call \p rocsparse_sbsrilu0, \p rocsparse_dbsrilu0,
|
|
* \p rocsparse_cbsrilu0, or \p rocsparse_zbsrilu0 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 rocsparse_sbsrilu0 "rocsparse_Xbsrilu0()" are complete, the temporary
|
|
* buffer can be deallocated.
|
|
*
|
|
* \p rocsparse_bsrilu0 reports the first zero pivot (either numerical or structural zero).
|
|
* The zero pivot status can be obtained by calling \ref rocsparse_bsrilu0_zero_pivot().
|
|
*
|

|
|
* This function is non-blocking and executed asynchronously with respect to the host.
|
