Detailed Description
TRTRI_STRIDED_BATCHED inverts a batch of triangular n-by-n matrices \(A_j\).
\(A_j\) can be upper or lower triangular, depending on the value of uplo, and unit or non-unit triangular, depending on the value of diag.
- Parameters
-
[in] handle rocblas_handle. [in] uplo rocblas_fill.
Specifies whether the upper or lower part of the matrices A_j are stored. If uplo indicates lower (or upper), then the upper (or lower) part of A_j is not used.[in] diag rocblas_diagonal.
If diag indicates unit, then the diagonal elements of matrices A_j are not referenced and assumed to be one.[in] n rocblas_int. n >= 0.
The number of rows and columns of all matrices A_j in the batch.[in,out] A pointer to type. Array on the GPU (the size depends on the value of strideA).
On entry, the triangular matrices A_j. On exit, the inverses of A_j if info[j] = 0.[in] lda rocblas_int. lda >= n.
Specifies the leading dimension of matrices A_j.[in] strideA rocblas_stride.
Stride from the start of one matrix A_j to the next one A_(j+1). There is no restriction for the value of strideA. Normal use case is strideA >= lda*n[out] info pointer to rocblas_int. Array of batch_count integers on the GPU.
If info[j] = 0, successful exit for inversion of A_j. If info[j] = i > 0, A_j is singular. A_j[i,i] is the first zero element in the diagonal.[in] batch_count rocblas_int. batch_count >= 0.
Number of matrices in the batch.
