integer(kind(hipblas_status_success)) function hipblasstrtribatched_ (handle, uplo, diag, n, ap, lda, inva, ldinva, batchcount)
 

Detailed Description

BLAS Level 3 API.

The trtriBatched 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 array of device pointers storing each matrix A_i.
[in]lda- [int] specifies the leading dimension of each A_i.
[out]invA- device array of device pointers storing the inverse 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]batchCount- [int] numbers of matrices in the batch.
