Detailed Description
BLAS Level 2 API.
hpmv performs the matrixvector operation
y := alpha*A*x + beta*y
where alpha and beta are scalars, x and y are n element vectors and A is an n by n Hermitian matrix, supplied in packed form (see description below).
 Parameters

[in] handle [rocblas_handle] handle to the rocblas library context queue. [in] uplo [rocblas_fill] rocblas_fill_upper: the upper triangular part of the Hermitian matrix A is supplied in AP. rocblas_fill_lower: the lower triangular part of the Hermitian matrix A is supplied in AP. [in] n [rocblas_int] the order of the matrix A, must be >= 0. [in] alpha device pointer or host pointer to scalar alpha. [in] AP device pointer storing the packed version of the specified triangular portion of the Hermitian matrix A. Of at least size ((n * (n + 1)) 2). if uplo == rocblas_fill_upper: The upper triangular portion of the Hermitian matrix A is supplied. The matrix is compacted so that AP contains the triangular portion columnbycolumn so that: AP(0) = A(0,0) AP(1) = A(0,1) AP(2) = A(1,1), etc. Ex: (rocblas_fill_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 == rocblas_fill_lower: The lower triangular portion of the Hermitian matrix A is supplied. The matrix is compacted so that AP contains the triangular portion columnbycolumn so that: AP(0) = A(0,0) AP(1) = A(1,0) AP(2) = A(2,1), etc. Ex: (rocblas_fill_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] x device pointer storing vector x. [in] incx [rocblas_int] specifies the increment for the elements of x. [in] beta device pointer or host pointer to scalar beta. [in,out] y device pointer storing vector y. [in] incy [rocblas_int] specifies the increment for the elements of y.
