Detailed Description
!
BLAS Level 2 API
\details
xHEMV performs one of the matrix-vector operations
y := alphaAx + betay
where alpha and beta are scalars, x and y are n element vectors and A is an
n by n Hermitian matrix.
@param[in]
handle [rocblas_handle]
handle to the rocblas library context queue.
@param[in]
uplo [rocblas_fill]
rocblas_fill_upper: the upper triangular part of the Hermitian matrix A is supplied.
rocblas_fill_lower: the lower triangular part of the Hermitian matrix A is supplied.
@param[in]
n [rocblas_int]
the order of the matrix A.
@param[in]
alpha device pointer or host pointer to scalar alpha.
@param[in]
A device pointer storing matrix A. Of dimension (lda, n).
if uplo == rocblas_fill_upper:
The upper triangular part of A must contain
the upper triangular part of a Hermitian matrix. The lower
triangular part of A will not be referenced.
if uplo == rocblas_fill_lower:
The lower triangular part of A must contain
the lower triangular part of a Hermitian matrix. The upper
triangular part of A will not be referenced.
As a Hermitian matrix, the imaginary part of the main diagonal
of A will not be referenced and is assumed to be == 0.
@param[in]
lda [rocblas_int]
specifies the leading dimension of A. must be >= max(1, n)
@param[in]
x device pointer storing vector x.
@param[in]
incx [rocblas_int]
specifies the increment for the elements of x.
@param[in]
beta device pointer or host pointer to scalar beta.
@param[inout]
y device pointer storing vector y.
@param[in]
incy [rocblas_int]
specifies the increment for the elements of y.
