CUNGLQ(l)		LAPACK routine (version	1.1)		    CUNGLQ(l)

NAME
  CUNGLQ - generate an M-by-N complex matrix Q with orthonormal	rows,

SYNOPSIS

  SUBROUTINE CUNGLQ( M,	N, K, A, LDA, TAU, WORK, LWORK,	INFO )

      INTEGER	     INFO, K, LDA, LWORK, M, N

      COMPLEX	     A(	LDA, * ), TAU( * ), WORK( LWORK	)

PURPOSE
  CUNGLQ 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(2)'	H(1)'

  as returned by CGELQF.

ARGUMENTS

  M	  (input) INTEGER
	  The number of	rows of	the matrix Q. M	>= 0.

  N	  (input) INTEGER
	  The number of	columns	of the matrix Q. N >= M.

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

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

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

  WORK	  (workspace) COMPLEX array, dimension (LWORK)
	  On exit, if INFO = 0,	WORK(1)	returns	the optimal LWORK.

  LWORK	  (input) INTEGER
	  The dimension	of the array WORK. LWORK >= max(1,M).  For optimum
	  performance LWORK >= M*NB, where NB is the optimal blocksize.

  INFO	  (output) INTEGER
	  = 0:	successful exit;
	  < 0:	if INFO	= -i, the i-th argument	has an illegal value
