Detailed Description

!

BLAS Level 3 API

\details

hemm performs one of the matrix-matrix operations:

C := alphaAB + betaC if side == rocblas_side_left,
C := alphaBA + betaC if side == rocblas_side_right,

where alpha and beta are scalars, B and C are m by n matrices, and
A is a Hermitian matrix stored as either upper or lower.

@param[in]
handle    [rocblas_handle]
          handle to the rocblas library context queue.

@param[in]
side  [rocblas_side]
        rocblas_side_left:      C := alphaAB + betaC
        rocblas_side_right:     C := alphaBA + betaC

@param[in]
uplo    [rocblas_fill]
        rocblas_fill_upper:  A is an upper triangular matrix
        rocblas_fill_lower:  A is a  lower triangular matrix

@param[in]
m       [rocblas_int]
        m specifies the number of rows of B and C. m >= 0.

@param[in]
n       [rocblas_int]
        n specifies the number of columns of B and C. n >= 0.

@param[in]
alpha
        alpha specifies the scalar alpha. When alpha is
        zero then A and B are not referenced.

@param[in]
A       pointer storing matrix A on the GPU.
        A is m by m if side == rocblas_side_left
        A is n by n if side == rocblas_side_right
        Only the upperlower triangular part is accessed.
        The imaginary component of the diagonal elements is not used.

@param[in]
lda     [rocblas_int]
        lda specifies the first dimension of A.
        if side = rocblas_side_left,  lda >= max( 1, m ),
        otherwise lda >= max( 1, n ).

@param[in]
B       pointer storing matrix B on the GPU.
        Matrix dimension is m by n

@param[in]
ldb     [rocblas_int]
        ldb specifies the first dimension of B. ldb >= max( 1, m )

@param[in]
beta
        beta specifies the scalar beta. When beta is
        zero then C need not be set before entry.

@param[in]
C       pointer storing matrix C on the GPU.
        Matrix dimension is m by n

@param[in]
ldc    [rocblas_int]
       ldc specifies the first dimension of C. ldc >= max( 1, m )
