Detailed Description

BLAS Level 2 API.

syr2Batched performs a batch of matrix-vector operations

A[i] := A[i] + alpha*x[i]*y[i]**T + alpha*y[i]*x[i]**T

where alpha is a scalar, x[i] and y[i] are vectors, and A[i] is a n by n symmetric 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' if HIPBLAS_FILL_MODE_UPPER, the lower part of A is not referenced if HIPBLAS_FILL_MODE_LOWER, the upper part of A is not referenced
[in]n[int] the number of rows and columns of matrix A.
[in]alphadevice pointer or host pointer to scalar alpha.
[in]xdevice array of device pointers storing each vector x_i.
[in]incx[int] specifies the increment for the elements of each x_i.
[in]ydevice array of device pointers storing each vector y_i.
[in]incy[int] specifies the increment for the elements of each y_i.
[in,out]Adevice array of device pointers storing each matrix A_i.
[in]lda[int] specifies the leading dimension of each A_i.
[in]batchCount[int] number of instances in the batch
