| integer(kind(rocblas_status_success)) function | rocblas_ssyr_batched_ (handle, uplo, n, alpha, x, incx, a, lda, batch_count) |
Detailed Description
BLAS Level 2 API.
The syr_batched functions perform 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 either 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,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.
