Detailed Description
The TRTRI_BATCHED functions invert a batch of triangular n -by-n matrices \(A_l\).
\(A_l\) 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_l are stored. If uplo indicates lower (or upper), then the upper (or lower) part of A_l is not used. [in] diag - rocblas_diagonal. If diag indicates unit, then the diagonal elements of matrices A_l are not referenced and assumed to equal one. [in] n - rocblas_int. n >= 0. The number of rows and columns of all matrices A_l in the batch. [in,out] A - array of pointers to type. Each pointer points to an array on the GPU of dimension lda*n. On entry, the triangular matrices A_l. On exit, the inverses of A_l if info[l] = 0. [in] lda - rocblas_int. lda >= n. Specifies the leading dimension of matrices A_l. [out] myInfo - pointer to rocblas_int. Array of batch_count integers on the GPU. If info[l] = 0, successful exit for inversion of A_l. If info[l] = i > 0, A_l is singular. A_l[i,i] is the first zero element in the diagonal. [in] batch_count - rocblas_int. batch_count >= 0. Number of matrices in the batch.
