NAME
       sorbdb6.f -

SYNOPSIS
   Functions/Subroutines
       subroutine sorbdb6 (M1, M2, N, X1, INCX1, X2, INCX2, Q1, LDQ1, Q2,
	   LDQ2, WORK, LWORK, INFO)
	   SORBDB6

Function/Subroutine Documentation
   subroutine sorbdb6 (integerM1, integerM2, integerN, real, dimension(*)X1,
       integerINCX1, real, dimension(*)X2, integerINCX2, real,
       dimension(ldq1,*)Q1, integerLDQ1, real, dimension(ldq2,*)Q2,
       integerLDQ2, real, dimension(*)WORK, integerLWORK, integerINFO)
       SORBDB6 .SH "Purpose:"

	SORBDB6 orthogonalizes the column vector
	     X = [ X1 ]
		 [ X2 ]
	with respect to the columns of
	     Q = [ Q1 ] .
		 [ Q2 ]
	The columns of Q must be orthonormal.

	If the projection is zero according to Kahan's "twice is enough"
	criterion, then the zero vector is returned..fi

       Parameters:
	   M1

		     M1 is INTEGER
		      The dimension of X1 and the number of rows in Q1. 0 <= M1.

	   M2

		     M2 is INTEGER
		      The dimension of X2 and the number of rows in Q2. 0 <= M2.

	   N

		     N is INTEGER
		      The number of columns in Q1 and Q2. 0 <= N.

	   X1

		     X1 is REAL array, dimension (M1)
		      On entry, the top part of the vector to be orthogonalized.
		      On exit, the top part of the projected vector.

	   INCX1

		     INCX1 is INTEGER
		      Increment for entries of X1.

	   X2

		     X2 is REAL array, dimension (M2)
		      On entry, the bottom part of the vector to be
		      orthogonalized. On exit, the bottom part of the projected
		      vector.

	   INCX2

		     INCX2 is INTEGER
		      Increment for entries of X2.

	   Q1

		     Q1 is REAL array, dimension (LDQ1, N)
		      The top part of the orthonormal basis matrix.

	   LDQ1

		     LDQ1 is INTEGER
		      The leading dimension of Q1. LDQ1 >= M1.

	   Q2

		     Q2 is REAL array, dimension (LDQ2, N)
		      The bottom part of the orthonormal basis matrix.

	   LDQ2

		     LDQ2 is INTEGER
		      The leading dimension of Q2. LDQ2 >= M2.

	   WORK

		     WORK is REAL array, dimension (LWORK)

	   LWORK

		     LWORK is INTEGER
		      The dimension of the array WORK. LWORK >= N.

	   INFO

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