Detailed Description
BLAS Level 2 API.
syr2_batched 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 , ... , 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] alpha device pointer or host pointer to scalar alpha. [in] x device array of device pointers storing each vector x_i. [in] incx [rocblas_int] specifies the increment for the elements of each x_i. [in] y device array of device pointers storing each vector y_i. [in] incy [rocblas_int] specifies the increment for the elements of each y_i. [in,out] A device 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
