Detailed Description
BLAS Level 2 API.
The syr2 functions perform the matrix-vector operations:
A := A + alpha*x*y**T + alpha*y*x**T
where alpha is a scalar, x and y are vectors, and A is an n by n symmetric matrix.
- 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 pointer storing vector x. [in] incx - [rocblas_int] specifies the increment for the elements of x. [in] y - device pointer storing vector y. [in] incy - [rocblas_int] specifies the increment for the elements of y. [in,out] A - device pointer storing matrix A. [in] lda - [rocblas_int] specifies the leading dimension of A.
