NAME
       dorgl2.f -

SYNOPSIS
   Functions/Subroutines
       subroutine dorgl2 (M, N, K, A, LDA, TAU, WORK, INFO)
	   DORGL2

Function/Subroutine Documentation
   subroutine dorgl2 (integerM, integerN, integerK, double precision, dimension( lda, * )A, integerLDA, double precision, dimension( * )TAU,
       double precision, dimension( * )WORK, integerINFO)
       DORGL2

       Purpose:

	    DORGL2 generates an m by n real 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 DGELQF.

       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 DOUBLE PRECISION 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 DGELQF 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 DOUBLE PRECISION array, dimension (K)
		     TAU(i) must contain the scalar factor of the elementary
		     reflector H(i), as returned by DGELQF.

	   WORK

		     WORK is DOUBLE PRECISION array, dimension (M)

	   INFO

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