NAME

       clanht.f -

SYNOPSIS

   Functions/Subroutines
       REAL function clanht (NORM, N, D, E)
	   CLANHT

Function/Subroutine Documentation
   REAL function clanht (characterNORM, integerN, real, dimension( * )D, complex, dimension( * )E)
       CLANHT

       Purpose:

	    CLANHT  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 tridiagonal matrix A.

       Returns:
	   CLANHT

	       CLANHT = ( 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 CLANHT as described
		     above.

	   N

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

	   D

		     D is REAL array, dimension (N)
		     The diagonal elements of A.

	   E

		     E is COMPLEX array, dimension (N-1)
		     The (n-1) sub-diagonal or super-diagonal elements of A.

Function/Subroutine Documentation
   REAL function slangt (characterNORM, integerN, real, dimension( * )DL, real, dimension( * )D, real, dimension( * )DU)
       SLANGT

       Purpose:

	    SLANGT  returns the value of the one norm,	or the Frobenius norm, or
	    the  infinity norm,  or the  element of  largest absolute value  of a
	    real tridiagonal matrix A.

			(
			( 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 SLANGT as described
		     above.

	   N

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

	   DL

		     DL is REAL array, dimension (N-1)
		     The (n-1) sub-diagonal elements of A.

	   D

		     D is REAL array, dimension (N)
		     The diagonal elements of A.

	   DU

		     DU is REAL array, dimension (N-1)
		     The (n-1) super-diagonal elements of A.
