NAME

       zlantp.f -

SYNOPSIS

   Functions/Subroutines
       DOUBLE PRECISION function zlantp (NORM, UPLO, DIAG, N, AP, WORK)
	   ZLANTP

Function/Subroutine Documentation
   DOUBLE PRECISION function zlantp (characterNORM, characterUPLO, characterDIAG, integerN, complex*16, dimension( * )AP, double precision,
       dimension( * )WORK)
       ZLANTP

       Purpose:

	    ZLANTP  returns the value of the one norm,	or the Frobenius norm, or
	    the  infinity norm,  or the  element of  largest absolute value  of a
	    triangular matrix A, supplied in packed form.

       Returns:
	   ZLANTP

	       ZLANTP = ( 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 consistent matrix norm.

       Parameters:
	   NORM

		     NORM is CHARACTER*1
		     Specifies the value to be returned in ZLANTP as described
		     above.

	   UPLO

		     UPLO is CHARACTER*1
		     Specifies whether the matrix A is upper or lower triangular.
		     = 'U':  Upper triangular
		     = 'L':  Lower triangular

	   DIAG

		     DIAG is CHARACTER*1
		     Specifies whether or not the matrix A is unit triangular.
		     = 'N':  Non-unit triangular
		     = 'U':  Unit triangular

	   N

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

	   AP

		     AP is COMPLEX*16 array, dimension (N*(N+1)/2)
		     The upper or lower triangular 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 when DIAG = 'U', the elements of the array AP
		     corresponding to the diagonal elements of the matrix A are
		     not referenced, but are assumed to be one.

	   WORK

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