Detailed Description

BLAS Level 2 API.

her performs the matrix-vector operations

A := A + alpha*x*x**H

where alpha is a real scalar, x is a vector, 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 in A. rocblas_fill_lower: The lower triangular part of A is supplied in A.
[in]n[rocblas_int] the number of rows and columns of matrix A, must be at least 0.
[in]alphadevice pointer or host pointer to scalar alpha.
[in]xdevice pointer storing vector x.
[in]incx[rocblas_int] specifies the increment for the elements of x.
[in,out]Adevice 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 triangluar portion will not be touched. if uplo == rocblas_fill_lower: The lower triangular portion of the Hermitian matrix A is supplied. The upper triangular portion 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(1, n).
