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 ≤ 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, andz. - 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.
