Detailed Description

BLAS Level 3 API.

The trtri_strided_batched functions compute the inverse of A_i and write into invA_i, where A_i and invA_i are the i-th matrices in the batch, for i = 1, ..., batch_count.

Parameters

[in]	handle	- [rocblas_handle] handle to the rocBLAS library context queue.
[in]	uplo	- [rocblas_fill] specifies whether upper (rocblas_fill_upper) or lower (rocblas_fill_lower).
[in]	diag	- [rocblas_diagonal] 'rocblas_diagonal_non_unit': A is non-unit triangular. 'rocblas_diagonal_unit': A is unit triangular.
[in]	n	- [rocblas_int]
[in]	A	- device pointer pointing to address of first matrix A_1.
[in]	lda	- [rocblas_int] specifies the leading dimension of each A.
[in]	stride_a	- [rocblas_stride] "batch stride a": stride from the start of one A_i matrix to the next A_(i + 1).
[out]	invA	- device pointer storing the inverses of each matrix A_i. Partial inplace operation is supported. See below: If UPLO = 'U', the leading N-by-N upper triangular part of the invA will store the inverse of the upper triangular matrix, and the strictly lower triangular part of invA can be cleared. If UPLO = 'L', the leading N-by-N lower triangular part of the invA will store the inverse of the lower triangular matrix, and the strictly upper triangular part of invA can be cleared.
[in]	ldinvA	- [rocblas_int] specifies the leading dimension of each invA_i.
[in]	stride_invA	- [rocblas_stride] "batch stride invA": stride from the start of one invA_i matrix to the next invA_(i + 1).
[in]	batch_count	- [rocblas_int] numbers of matrices in the batch.
