integer(kind(hipblas_status_success)) function hipblasstpmvbatched_ (handle, uplo, transa, diag, n, ap, x, incx, batchcount)
 

Detailed Description

BLAS Level 2 API.

The tpmvBatched functions perform one of the matrix-vector operations: 

 x_i = A_i*x_i or x_i = A**T*x_i, 0 &le; i < batchCount

where x_i is an n -element vector and A_i is an n by n (unit, or non-unit, upper or lower triangular matrix).

The vectors x_i are overwritten.

  • 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]
  • HIPBLAS_FILL_MODE_UPPER: A_i is an upper triangular matrix.
  • HIPBLAS_FILL_MODE_LOWER: A_i is a lower triangular matrix.
[in]transA- [hipblasOperation_t]
[in]diag- [hipblasDiagType_t]
  • HIPBLAS_DIAG_UNIT: A_i is assumed to be unit triangular.
  • HIPBLAS_DIAG_NON_UNIT: A_i is not assumed to be unit triangular.
[in]n- [int] n specifies the number of rows of matrices A_i. n >= 0.
[in]AP- device pointer storing pointer of matrices A_i of dimension ( lda, n ).
[in]x- device pointer storing vectors x_i.
[in]incx- [int] specifies the increment for the elements of vectors x_i.
[in]batchCount- [int] The number of batched matrices/vectors.
