SYNOPSIS
   Functions/Subroutines
       subroutine slasq5 (I0, N0, Z, PP, TAU, SIGMA, DMIN, DMIN1, DMIN2, DN, DNM1, DNM2, IEEE,
	   EPS)
	   SLASQ5 computes one dqds transform in ping-pong form. Used by sbdsqr and sstegr.

Function/Subroutine Documentation
   subroutine slasq5 (integerI0, integerN0, real, dimension( * )Z, integerPP, realTAU, realSIGMA,
       realDMIN, realDMIN1, realDMIN2, realDN, realDNM1, realDNM2, logicalIEEE, realEPS)
       SLASQ5 computes one dqds transform in ping-pong form. Used by sbdsqr and sstegr.

       Purpose:

	    SLASQ5 computes one dqds transform in ping-pong form, one
	    version for IEEE machines another for non IEEE machines.

       Parameters:
	   I0

		     I0 is INTEGER
		   First index.

	   N0

		     N0 is INTEGER
		   Last index.

	   Z

		     Z is REAL array, dimension ( 4*N )
		   Z holds the qd array. EMIN is stored in Z(4*N0) to avoid
		   an extra argument.

	   PP

		     PP is INTEGER
		   PP=0 for ping, PP=1 for pong.

	   TAU

		     TAU is REAL
		   This is the shift.

	   DMIN

		     DMIN is REAL
		   Minimum value of d.

	   DMIN1

		     DMIN1 is REAL
		   Minimum value of d, excluding D( N0 ).

	   DMIN2

		     DMIN2 is REAL
		   Minimum value of d, excluding D( N0 ) and D( N0-1 ).

	   DN

		     DN is REAL
		   d(N0), the last value of d.

	   DNM1

		     DNM1 is REAL
		   d(N0-1).

	   DNM2

		     DNM2 is REAL
		   d(N0-2).

	   IEEE

		     IEEE is LOGICAL
		   Flag for IEEE or non IEEE arithmetic.
