Detailed Description
BLAS Level 2 API.
hpmvStridedBatched performs the matrix-vector operation
y_i := alpha*A_i*x_i + beta*y_i
where alpha and beta are scalars, x_i and y_i are n element vectors and A_i is an n by n Hermitian matrix, supplied in packed form (see description below), for each batch in i = [1, batchCount].
- Parameters
-
[in] handle [hipblasHandle_t] handle to the hipblas library context queue. [in] uplo [hipblasFillMode_t] HIPBLAS_FILL_MODE_UPPER: the upper triangular part of each Hermitian matrix A_i is supplied in AP. HIPBLAS_FILL_MODE_LOWER: the lower triangular part of each Hermitian matrix A_i is supplied in AP. [in] n [int] the order of each matrix A_i. [in] alpha device pointer or host pointer to scalar alpha. [in] AP device pointer pointing to the beginning of the first matrix (AP_1). Stores the packed version of the specified triangular portion of each Hermitian matrix AP_i of size ((n * (n + 1)) 2). if uplo == HIPBLAS_FILL_MODE_UPPER: The upper triangular portion of each Hermitian matrix A_i is supplied. The matrix is compacted so that each AP_i contains the triangular portion column-by-column so that: AP(0) = A(0,0) AP(1) = A(0,1) AP(2) = A(1,1), etc. Ex: (HIPBLAS_FILL_MODE_UPPER; n = 3) (1, 0) (2, 1) (3, 2) (2,-1) (4, 0) (5,-1) --—> [(1,0), (2,1), (4,0), (3,2), (5,-1), (6,0)] (3,-2) (5, 1) (6, 0) if uplo == HIPBLAS_FILL_MODE_LOWER: The lower triangular portion of each Hermitian matrix A_i is supplied. The matrix is compacted so that each AP_i contains the triangular portion column-by-column so that: AP(0) = A(0,0) AP(1) = A(1,0) AP(2) = A(2,1), etc. Ex: (HIPBLAS_FILL_MODE_LOWER; n = 3) (1, 0) (2, 1) (3, 2) (2,-1) (4, 0) (5,-1) --—> [(1,0), (2,-1), (3,-2), (4,0), (5,1), (6,0)] (3,-2) (5, 1) (6, 0) Note that the imaginary part of the diagonal elements are not accessed and are assumed to be 0. [in] strideA [hipblasStride] stride from the start of one matrix (AP_i) and the next one (AP_i+1). [in] x device array pointing to the beginning of the first vector (x_1). [in] incx [int] specifies the increment for the elements of each x_i. [in] stridex [hipblasStride] stride from the start of one vector (x_i) and the next one (x_i+1). [in] beta device pointer or host pointer to scalar beta. [in,out] y device array pointing to the beginning of the first vector (y_1). [in] incy [int] specifies the increment for the elements of y. [in] stridey [hipblasStride] stride from the start of one vector (y_i) and the next one (y_i+1). [in] batchCount [int] number of instances in the batch.
