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]handlerocblas_handle.
[in]uplorocblas_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]diagrocblas_diagonal.
If diag indicates unit, then the diagonal elements of matrices A_j are not referenced and assumed to be one.
[in]nrocblas_int. n >= 0.
The number of rows and columns of all matrices A_j in the batch.
[in,out]Apointer 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]ldarocblas_int. lda >= n.
Specifies the leading dimension of matrices A_j.
[in]strideArocblas_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]infopointer 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_countrocblas_int. batch_count >= 0.
Number of matrices in the batch.
