*> \par Purpose:
*  =============
*>
*> \verbatim
*>
*> CLANHF  returns the value of the one norm,  or the Frobenius norm, or
*> the  infinity norm,  or the  element of  largest absolute value  of a
*> complex Hermitian matrix A in RFP format.
*> \endverbatim
*>
*> \return CLANHF
*> \verbatim
*>
*>    CLANHF = ( max(abs(A(i,j))), NORM = 'M' or 'm'
*>             (
*>             ( norm1(A),         NORM = '1', 'O' or 'o'
*>             (
*>             ( normI(A),         NORM = 'I' or 'i'
*>             (
*>             ( normF(A),         NORM = 'F', 'f', 'E' or 'e'
*>
*> where  norm1  denotes the  one norm of a matrix (maximum column sum),
*> normI  denotes the  infinity norm  of a matrix  (maximum row sum) and
*> normF  denotes the  Frobenius norm of a matrix (square root of sum of
*> squares).  Note that  max(abs(A(i,j)))  is not a  matrix norm.
*> \endverbatim
*
*  Arguments:
*  ==========
*
*> \param[in] NORM
*> \verbatim
*>          NORM is CHARACTER
*>            Specifies the value to be returned in CLANHF as described
*>            above.
*> \endverbatim
*>
*> \param[in] TRANSR
*> \verbatim
*>          TRANSR is CHARACTER
*>            Specifies whether the RFP format of A is normal or
*>            conjugate-transposed format.
*>            = 'N':  RFP format is Normal
*>            = 'C':  RFP format is Conjugate-transposed
*> \endverbatim
*>
*> \param[in] UPLO
*> \verbatim
*>          UPLO is CHARACTER
*>            On entry, UPLO specifies whether the RFP matrix A came from
*>            an upper or lower triangular matrix as follows:
*>
*>            UPLO = 'U' or 'u' RFP A came from an upper triangular
*>            matrix
*>
*>            UPLO = 'L' or 'l' RFP A came from a  lower triangular
*>            matrix
*> \endverbatim
*>
*> \param[in] N
*> \verbatim
*>          N is INTEGER
*>            The order of the matrix A.  N >= 0.  When N = 0, CLANHF is
*>            set to zero.
*> \endverbatim
*>
*> \param[in] A
*> \verbatim
*>          A is COMPLEX array, dimension ( N*(N+1)/2 );
*>            On entry, the matrix A in RFP Format.
*>            RFP Format is described by TRANSR, UPLO and N as follows:
*>            If TRANSR='N' then RFP A is (0:N,0:K-1) when N is even;
*>            K=N/2. RFP A is (0:N-1,0:K) when N is odd; K=N/2. If
*>            TRANSR = 'C' then RFP is the Conjugate-transpose of RFP A
*>            as defined when TRANSR = 'N'. The contents of RFP A are
*>            defined by UPLO as follows: If UPLO = 'U' the RFP A
*>            contains the ( N*(N+1)/2 ) elements of upper packed A
*>            either in normal or conjugate-transpose Format. If
*>            UPLO = 'L' the RFP A contains the ( N*(N+1) /2 ) elements
*>            of lower packed A either in normal or conjugate-transpose
*>            Format. The LDA of RFP A is (N+1)/2 when TRANSR = 'C'. When
*>            TRANSR is 'N' the LDA is N+1 when N is even and is N when
*>            is odd. See the Note below for more details.
*>            Unchanged on exit.
*> \endverbatim
*>
*> \param[out] WORK
*> \verbatim
*>          WORK is REAL array, dimension (LWORK),
*>            where LWORK >= N when NORM = 'I' or '1' or 'O'; otherwise,
*>            WORK is not referenced.
