BLAS Level 2 API.

her_batched performs the matrix-vector operations

A_i := A_i + alpha*x_i*x_i**H

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.

Parameters

[in]	handle	[rocblas_handle] handle to the rocblas library context queue.
[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.
[in]	n	[rocblas_int] the number of rows and columns of each matrix A_i, must be at least 0.
[in]	alpha	device pointer or host pointer to scalar alpha.
[in]	x	device array of device pointers storing each vector x_i.
[in]	incx	[rocblas_int] specifies the increment for the elements of each x_i.
[in,out]	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.
[in]	lda	[rocblas_int] specifies the leading dimension of each A_i. Must be at least max(1, n).
[in]	batch_count	[rocblas_int] number of instances in the batch.
