Detailed Description
BLAS Level 2 API.
her2 performs the matrix-vector operations
A := A + alpha*x*y**H + conj(alpha)*y*x**H
where alpha is a complex scalar, x and y are vectors, and A is an n by n Hermitian matrix.
- 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' rocblas_fill_upper: The upper triangular part of A is supplied. rocblas_fill_lower: The lower triangular part of A is supplied. [in] n [rocblas_int] the number of rows and columns of matrix A, must be at least 0. [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 the specified triangular portion of the Hermitian matrix A. Of size (lda, n). if uplo == rocblas_fill_upper: The upper triangular portion of the Hermitian matrix A is supplied. The lower triangular portion of A will not be touched. if uplo == rocblas_fill_lower: The lower triangular portion of the Hermitian matrix A is supplied. The upper triangular portion of A will not be touched. Note that the imaginary part of the diagonal elements are not accessed and are assumed to be 0. [in] lda [rocblas_int] specifies the leading dimension of A. Must be at least max(lda, 1).
