Detailed Description

!

BLAS Level 2 API

\details
xHER performs the matrix-vector operations

    A := A + alphaxxH

where alpha is a real scalar, x is a vector, and A is an
n by n Hermitian matrix.

@param[in]
handle    [rocblas_handle]
          handle to the rocblas library context queue.
@param[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.
@param[in]
n         [rocblas_int]
          the number of rows and columns of matrix A, must be at least 0.
@param[in]
alpha
          device pointer or host pointer to scalar alpha.
@param[in]
x         device pointer storing vector x.
@param[in]
incx      [rocblas_int]
          specifies the increment for the elements of x.
@param[inout]
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
            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.
@param[in]
lda       [rocblas_int]
          specifies the leading dimension of A. Must be at least max(1, n).
