## Detailed Description

BLAS Level 2 API.

syr2_strided_batched the 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 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 each matrix A. [in] alpha device pointer or host pointer to scalar alpha. [in] x device pointer to the first vector x_1. [in] incx [rocblas_int] specifies the increment for the elements of each x_i. [in] stridex [rocblas_stride] specifies the pointer increment between vectors (x_i) and (x_i+1). [in] y device pointer to the first vector y_1. [in] incy [rocblas_int] specifies the increment for the elements of each y_i. [in] stridey [rocblas_stride] specifies the pointer increment between vectors (y_i) and (y_i+1). [in,out] A device pointer to the first matrix A_1. [in] lda [rocblas_int] specifies the leading dimension of each A_i. [in] strideA [rocblas_stride] stride from the start of one matrix (A_i) and the next one (A_i+1) [in] batch_count [rocblas_int] number of instances in the batch
