Detailed Description

BLAS Level 2 API.

herStridedBatched 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 Hermitian matrix, for i = 1, ..., batchCount.

Parameters
[in]handle[hipblasHandle_t] handle to the hipblas library context queue.
[in]uplo[hipblasFillMode_t] specifies whether the upper 'HIPBLAS_FILL_MODE_UPPER' or lower 'HIPBLAS_FILL_MODE_LOWER' HIPBLAS_FILL_MODE_UPPER: The upper triangular part of each A_i is supplied in A. HIPBLAS_FILL_MODE_LOWER: The lower triangular part of each A_i is supplied in A.
[in]n[int] the number of rows and columns of each matrix A_i, must be at least 0.
[in]alphadevice pointer or host pointer to scalar alpha.
[in]xdevice pointer pointing to the first vector (x_1).
[in]incx[int] specifies the increment for the elements of each x_i.
[in]stridex[hipblasStride] stride from the start of one vector (x_i) and the next one (x_i+1).
[in,out]Adevice array of device pointers storing the specified triangular portion of each Hermitian matrix A_i. Points to the first matrix (A_1). if uplo == HIPBLAS_FILL_MODE_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 == HIPBLAS_FILL_MODE_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[int] specifies the leading dimension of each A_i.
[in]strideA[hipblasStride] stride from the start of one (A_i) and the next (A_i+1)
[in]batchCount[int] number of instances in the batch.
