Detailed Description

BLAS Level 2 API.

The trmvStridedBatched 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, with strides specifying how to retrieve $x_i$ (resp. $A_i$ ) from $x_{i-1}$ (resp. $A_i$ ).

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 of the matrix A_0, of dimension ( lda, n ).
[in]lda- [int] specifies the leading dimension of A_i. lda >= max( 1, n ).
[in]strideA- [hipblasStride] stride from the start of one A_i matrix to the next A_{i + 1}.
[in]x- device pointer storing the vector x_0.
[in]incx- [int] specifies the increment for the elements of one vector x.
[in]stridex- [hipblasStride] stride from the start of one x_i vector to the next x_{i + 1}.
[in]batchCount- [int] The number of batched matrices/vectors.
