Detailed Description

BLAS Level 2 API.

syr_batched performs a batch of matrix-vector operations

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

where alpha is a scalar, x is an array of vectors, and A is an array of n by n symmetric matrices, 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' if rocblas_fill_upper, the lower part of A is not referenced if rocblas_fill_lower, the upper part of A is not referenced
[in]n[rocblas_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[rocblas_int] specifies the increment for the elements of each x_i.
[in,out]Adevice array of device pointers storing each matrix A_i.
[in]lda[rocblas_int] specifies the leading dimension of each A_i.
[in]batch_count[rocblas_int] number of instances in the batch
