Detailed Description

!

BLAS Level 2 API

\details
xSYR2_BATCHED performs a batch of matrix-vector operations

    A[i] := A[i] + alphax[i]y[i]T + alphay[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 , ... , batch_count

@param[in]
handle    [rocblas_handle]
          handle to the rocblas library context queue.
@param[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
@param[in]
n         [rocblas_int]
          the number of rows and columns of matrix A.
@param[in]
alpha
          device pointer or host pointer to scalar alpha.
@param[in]
x         device array of device pointers storing each vector x_i.
@param[in]
incx      [rocblas_int]
          specifies the increment for the elements of each x_i.
@param[in]
y         device array of device pointers storing each vector y_i.
@param[in]
incy      [rocblas_int]
          specifies the increment for the elements of each y_i.
@param[inout]
A         device array of device pointers storing each matrix A_i.
@param[in]
lda       [rocblas_int]
          specifies the leading dimension of each A_i.
@param[in]
batch_count [rocblas_int]
            number of instances in the batch
