integer(kind(rocsparse_status_success)) function	rocsparse_csrilu0_clear_ (handle, myInfo)

Detailed Description

Incomplete LU factorization with 0 fill-ins and no pivoting using CSR storage format.

rocsparse_csrilu0_clear deallocates all memory that was allocated by rocsparse_scsrilu0_analysis(), rocsparse_dcsrilu0_analysis(), rocsparse_ccsrilu0_analysis() or rocsparse_zcsrilu0_analysis(). This is especially useful, if memory is an issue and the analysis data is not required for further computation.

Note: Calling rocsparse_csrilu0_clear is optional. All allocated resources will be cleared, when the opaque rocsparse_mat_info struct is destroyed using rocsparse_destroy_mat_info().

Parameters

[in]	handle	handle to the rocsparse library context queue.
[in,out]	info	structure that holds the information collected during the analysis step.

Return values

rocsparse_status_success	the operation completed successfully.
rocsparse_status_invalid_handle	the library context was not initialized.
rocsparse_status_invalid_pointer	`info` pointer is invalid.
rocsparse_status_memory_error	the buffer holding the meta data could not be deallocated.
rocsparse_status_internal_error	an internal error occurred.
