CLANHP(l)			       )			     CLANHP(l)

NAME
       CLANHP  -  return  the value of the one norm, or the Frobenius norm, or
       the infinity norm, or the element of largest absolute value of  a  com‐
       plex hermitian matrix A, supplied in packed form

SYNOPSIS
       REAL FUNCTION CLANHP( NORM, UPLO, N, AP, WORK )

	   CHARACTER NORM, UPLO

	   INTEGER   N

	   REAL	     WORK( * )

	   COMPLEX   AP( * )

PURPOSE
       CLANHP 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, supplied in packed form.

DESCRIPTION
       CLANHP returns the value

	  CLANHP = ( 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.

ARGUMENTS
       NORM    (input) CHARACTER*1
	       Specifies the value to  be  returned  in	 CLANHP	 as  described
	       above.

       UPLO    (input) CHARACTER*1
	       Specifies  whether  the	upper  or lower triangular part of the
	       hermitian matrix A is supplied.	= 'U':	Upper triangular  part
	       of A is supplied
	       = 'L':  Lower triangular part of A is supplied

       N       (input) INTEGER
	       The  order of the matrix A.  N >= 0.  When N = 0, CLANHP is set
	       to zero.

       AP      (input) COMPLEX array, dimension (N*(N+1)/2)
	       The upper or lower triangle of the hermitian matrix  A,	packed
	       columnwise  in  a linear array.	The j-th column of A is stored
	       in the array AP as follows: if UPLO = 'U', AP(i + (j-1)*j/2)  =
	       A(i,j)  for  1<=i<=j;  if  UPLO = 'L', AP(i + (j-1)*(2n-j)/2) =
	       A(i,j) for j<=i<=n.  Note that  the   imaginary	parts  of  the
	       diagonal elements need not be set and are assumed to be zero.

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