Detailed Description
!
BLAS Level 2 API
\details
xHER2 performs the matrix-vector operations
A := A + alphaxyH + conj(alpha)yxH
where alpha is a complex scalar, x and y are 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]
specifies whether the upper 'rocblas_fill_upper' or lower 'rocblas_fill_lower'
rocblas_fill_upper: The upper triangular part of A is supplied.
rocblas_fill_lower: The lower triangular part of A is supplied.
@param[in]
n [rocblas_int]
the number of rows and columns of matrix A, must be at least 0.
@param[in]
alpha
device pointer or host pointer to scalar alpha.
@param[in]
x device pointer storing vector x.
@param[in]
incx [rocblas_int]
specifies the increment for the elements of x.
@param[in]
y device pointer storing vector y.
@param[in]
incy [rocblas_int]
specifies the increment for the elements of y.
@param[inout]
A device pointer storing the specified triangular portion of
the Hermitian matrix A. Of size (lda, n).
if uplo == rocblas_fill_upper:
The upper triangular portion of the Hermitian matrix A is supplied. The lower triangular
portion of A will not be touched.
if uplo == rocblas_fill_lower:
The lower triangular portion of the Hermitian matrix A is supplied. The upper triangular
portion of A will not be touched.
Note that the imaginary part of the diagonal elements are not accessed and are assumed
to be 0.
@param[in]
lda [rocblas_int]
specifies the leading dimension of A. Must be at least max(lda, 1).
