SYNOPSIS
   Functions/Subroutines
       subroutine cungl2 (M, N, K, A, LDA, TAU, WORK, INFO)
	   CUNGL2 generates all or part of the unitary matrix Q from an LQ factorization determined by cgelqf (unblocked algorithm).

Function/Subroutine Documentation
   subroutine cungl2 (integerM, integerN, integerK, complex, dimension( lda, * )A, integerLDA, complex, dimension( * )TAU, complex, dimension( *
       )WORK, integerINFO)
       CUNGL2 generates all or part of the unitary matrix Q from an LQ factorization determined by cgelqf (unblocked algorithm).

       Purpose:

	    CUNGL2 generates an m-by-n complex matrix Q with orthonormal rows,
	    which is defined as the first m rows of a product of k elementary
	    reflectors of order n

		  Q  =	H(k)**H . . . H(2)**H H(1)**H

	    as returned by CGELQF.

       Parameters:
	   M

		     M is INTEGER
		     The number of rows of the matrix Q. M >= 0.

	   N

		     N is INTEGER
		     The number of columns of the matrix Q. N >= M.

	   K

		     K is INTEGER
		     The number of elementary reflectors whose product defines the
		     matrix Q. M >= K >= 0.

	   A

		     A is COMPLEX array, dimension (LDA,N)
		     On entry, the i-th row must contain the vector which defines
		     the elementary reflector H(i), for i = 1,2,...,k, as returned
		     by CGELQF in the first k rows of its array argument A.
		     On exit, the m by n matrix Q.

	   LDA

		     LDA is INTEGER
		     The first dimension of the array A. LDA >= max(1,M).

	   TAU

		     TAU is COMPLEX array, dimension (K)
		     TAU(i) must contain the scalar factor of the elementary
		     reflector H(i), as returned by CGELQF.

	   WORK

		     WORK is COMPLEX array, dimension (M)

	   INFO

		     INFO is INTEGER
		     = 0: successful exit
		     < 0: if INFO = -i, the i-th argument has an illegal value
