Detailed Description
!
BLAS Level 2 API
\details
xHER_BATCHED performs the matrix-vector operations
A_i := A_i + alphax_ix_iH
where alpha is a real scalar, x_i is a vector, and A_i is an
n by n symmetric matrix, for i = 1, ..., batch_count.
@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 each A_i is supplied in A.
rocblas_fill_lower: The lower triangular part of each A_i is supplied in A.
@param[in]
n [rocblas_int]
the number of rows and columns of each matrix A_i, must be at least 0.
@param[in]
alpha
device pointer or host pointer to scalar alpha.
@param[in]
x device array of device pointers storing each vector x_i.
@param[in]
incx [rocblas_int]
specifies the increment for the elements of each x_i.
@param[inout]
A device array of device pointers storing the specified triangular portion of
each Hermitian matrix A_i of at least size ((n (n + 1)) 2). Array is of at least size batch_count.
if uplo == rocblas_fill_upper:
The upper triangular portion of each Hermitian matrix A_i is supplied. The lower triangular portion
of each A_i will not be touched.
if uplo == rocblas_fill_lower:
The lower triangular portion of each Hermitian matrix A_i is supplied. The upper triangular portion
of each A_i 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 each A_i. Must be at least max(1, n).
@param[in]
batch_count [rocblas_int]
number of instances in the batch.
