ZLANHF  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.

    ZLANHF = ( 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.

          NORM is CHARACTER
            Specifies the value to be returned in ZLANHF as described
            above.

          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

          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

          N is INTEGER
            The order of the matrix A.  N >= 0.  When N = 0, ZLANHF is
            set to zero.

          A is COMPLEX*16 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.

          WORK is DOUBLE PRECISION array, dimension (LWORK),
            where LWORK >= N when NORM = 'I' or '1' or 'O'; otherwise,
            WORK is not referenced.

  We first consider Standard Packed Format when N is even.
  We give an example where N = 6.

  Let TRANSR = 'N'. RFP holds AP as follows:
  For UPLO = 'U' the upper trapezoid A(0:5,0:2) consists of the last
  three columns of AP upper. The lower triangle A(4:6,0:2) consists of
  conjugate-transpose of the first three columns of AP upper.
  For UPLO = 'L' the lower trapezoid A(1:6,0:2) consists of the first
  three columns of AP lower. The upper triangle A(0:2,0:2) consists of
  conjugate-transpose of the last three columns of AP lower.
  To denote conjugate we place -- above the element. This covers the
  case N even and TRANSR = 'N'.

  Now let TRANSR = 'C'. RFP A in both UPLO cases is just the conjugate-
  transpose of RFP A above. One therefore gets:

  We next  consider Standard Packed Format when N is odd.
  We give an example where N = 5.

  Let TRANSR = 'N'. RFP holds AP as follows:
  For UPLO = 'U' the upper trapezoid A(0:4,0:2) consists of the last
  three columns of AP upper. The lower triangle A(3:4,0:1) consists of
  conjugate-transpose of the first two   columns of AP upper.
  For UPLO = 'L' the lower trapezoid A(0:4,0:2) consists of the first
  three columns of AP lower. The upper triangle A(0:1,1:2) consists of
  conjugate-transpose of the last two   columns of AP lower.
  To denote conjugate we place -- above the element. This covers the
  case N odd  and TRANSR = 'N'.

  Now let TRANSR = 'C'. RFP A in both UPLO cases is just the conjugate-
  transpose of RFP A above. One therefore gets:
