Detailed Description

BLAS Level 3 API.

The trtriStridedBatched 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, ..., batchCount.

• Supported precisions in rocBLAS : s, d, c, and z.
• Supported precisions in cuBLAS : No support.

Parameters

[in]	handle	- [hipblasHandle_t] handle to the hipBLAS library context queue.
[in]	uplo	- [hipblasFillMode_t] specifies either upper (HIPBLAS_FILL_MODE_UPPER) or lower (HIPBLAS_FILL_MODE_LOWER):
[in]	diag	- [hipblasDiagType_t] 'HIPBLAS_DIAG_NON_UNIT', A is non-unit triangular. 'HIPBLAS_DIAG_UNIT', A is unit triangular.
[in]	n	- [int]
[in]	AP	- device pointer pointing to address of first matrix A_1.
[in]	lda	- [int] specifies the leading dimension of each A.
[in]	strideA	- [hipblasStride] "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 is 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 is cleared.
[in]	ldinvA	- [int] specifies the leading dimension of each invA_i.
[in]	stride_invA	- [hipblasStride] "batch stride invA": stride from the start of one invA_i matrix to the next invA_(i + 1).
[in]	batchCount	- [int] numbers of matrices in the batch.
