DLARTG(3F)							    DLARTG(3F)

NAME
     DLARTG - generate a plane rotation so that	  [ CS SN ]

SYNOPSIS
     SUBROUTINE DLARTG( F, G, CS, SN, R )

	 DOUBLE		PRECISION CS, F, G, R, SN

PURPOSE
     DLARTG generate a plane rotation so that
	[ -SN  CS  ]	 [ G ]	   [ 0 ]

     This is a slower, more accurate version of the BLAS1 routine DROTG, with
     the following other differences:
	F and G are unchanged on return.
	If G=0, then CS=1 and SN=0.
	If F=0 and (G .ne. 0), then CS=0 and SN=1 without doing any
	   floating point operations (saves work in DBDSQR when
	   there are zeros on the diagonal).

     If F exceeds G in magnitude, CS will be positive.

ARGUMENTS
     F	     (input) DOUBLE PRECISION
	     The first component of vector to be rotated.

     G	     (input) DOUBLE PRECISION
	     The second component of vector to be rotated.

     CS	     (output) DOUBLE PRECISION
	     The cosine of the rotation.

     SN	     (output) DOUBLE PRECISION
	     The sine of the rotation.

     R	     (output) DOUBLE PRECISION
	     The nonzero component of the rotated vector.
