NAME
       cung2r.f -

SYNOPSIS
   Functions/Subroutines
       subroutine cung2r (M, N, K, A, LDA, TAU, WORK, INFO)
	   CUNG2R

Function/Subroutine Documentation
   subroutine cung2r (integerM, integerN, integerK, complex, dimension( lda, * )A, integerLDA, complex, dimension( * )TAU, complex, dimension( *
       )WORK, integerINFO)
       CUNG2R

       Purpose:

	    CUNG2R generates an m by n complex matrix Q with orthonormal columns,
	    which is defined as the first n columns of a product of k elementary
	    reflectors of order m

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

	    as returned by CGEQRF.

       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. M >= N >= 0.

	   K

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

	   A

		     A is COMPLEX array, dimension (LDA,N)
		     On entry, the i-th column must contain the vector which
		     defines the elementary reflector H(i), for i = 1,2,...,k, as
		     returned by CGEQRF in the first k columns 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 CGEQRF.

	   WORK

		     WORK is COMPLEX array, dimension (N)

	   INFO

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