zlaqr1.f(3)							      LAPACK							       zlaqr1.f(3)

NAME

       zlaqr1.f -

SYNOPSIS

   Functions/Subroutines
       subroutine zlaqr1 (N, H, LDH, S1, S2, V)
	   ZLAQR1 sets a scalar multiple of the first column of the product of 2-by-2 or 3-by-3 matrix H and specified shifts.

Function/Subroutine Documentation
   subroutine zlaqr1 (integerN, complex*16, dimension( ldh, * )H, integerLDH, complex*16S1, complex*16S2, complex*16, dimension( * )V)
       ZLAQR1 sets a scalar multiple of the first column of the product of 2-by-2 or 3-by-3 matrix H and specified shifts.

       Purpose:

		 Given a 2-by-2 or 3-by-3 matrix H, ZLAQR1 sets v to a
		 scalar multiple of the first column of the product

		 (*)  K = (H - s1*I)*(H - s2*I)

		 scaling to avoid overflows and most underflows.

		 This is useful for starting double implicit shift bulges
		 in the QR algorithm.

       Parameters:
	   N

		     N is integer
			 Order of the matrix H. N must be either 2 or 3.

	   H

		     H is COMPLEX*16 array of dimension (LDH,N)
			 The 2-by-2 or 3-by-3 matrix H in (*).

	   LDH

		     LDH is integer
			 The leading dimension of H as declared in
			 the calling procedure.  LDH.GE.N

	   S1

		     S1 is COMPLEX*16

	   S2

		     S2 is COMPLEX*16

		     S1 and S2 are the shifts defining K in (*) above.

	   V

		     V is COMPLEX*16 array of dimension N
			 A scalar multiple of the first column of the
			 matrix K in (*).
