Detailed Description
BLAS Level 2 API.
symv_batched performs the matrix-vector operation:
y_i := alpha*A_i*x_i + beta*y_i,
where (A_i, x_i, y_i) is the i-th instance of the batch. alpha and beta are scalars, x_i and y_i are vectors and A_i is an n by n symmetric matrix, for i = 1, ..., batch_count. A a should contain an upper or lower triangular symmetric matrix and the opposing triangular part of A is not referenced
- 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] number of rows and columns of each matrix A_i [in] alpha device pointer or host pointer to scalar alpha [in] A device array of device pointers storing each matrix A_i [in] lda [rocblas_int] specifies the leading dimension of each matrix A_i [in] x device array of device pointers storing each vector x_i [in] incx [rocblas_int] specifies the increment for the elements of each vector x_i [in] beta device pointer or host pointer to scalar beta [out] y device array of device pointers storing each vector y_i [in] incy [rocblas_int] specifies the increment for the elements of each vector y_i [in] batch_count [rocblas_int] number of instances in the batch
