Detailed Description

BLAS Level 3 API.

The trtri functions compute the inverse of a matrix A, namely, invA, and write the result into invA.

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): If rocblas_fill_upper, the lower part of A is not referenced. If rocblas_fill_lower, the upper part of A is not referenced.
[in]	diag	- [rocblas_diagonal] 'rocblas_diagonal_non_unit': A is non-unit triangular. 'rocblas_diagonal_unit': A is unit triangular.
[in]	n	- [rocblas_int] size of matrix A and invA.
[in]	A	- device pointer storing matrix A.
[in]	lda	- [rocblas_int] specifies the leading dimension of A.
[out]	invA	- device pointer storing matrix invA. 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 invA.
