CLASSQ(1)	    LAPACK auxiliary routine (version 3.2)	     CLASSQ(1)

NAME
       CLASSQ - returns the values scl and ssq such that   ( scl**2 )*ssq = x(
       1 )**2 +...+ x( n )**2 + ( scale**2 )*sumsq,

SYNOPSIS
       SUBROUTINE CLASSQ( N, X, INCX, SCALE, SUMSQ )

	   INTEGER	  INCX, N

	   REAL		  SCALE, SUMSQ

	   COMPLEX	  X( * )

PURPOSE
       CLASSQ returns the values scl and ssq such that where x( i ) = abs(  X(
       1  +  (	i - 1 )*INCX ) ). The value of sumsq is assumed to be at least
       unity and the value of ssq will then satisfy
	  1.0 .le. ssq .le. ( sumsq + 2*n ).
       scale is assumed to be non-negative and scl returns the value
	  scl = max( scale, abs( real( x( i ) ) ), abs( aimag( x( i ) ) ) ),
		 i
       scale and sumsq must be	supplied  in  SCALE  and  SUMSQ	 respectively.
       SCALE  and SUMSQ are overwritten by scl and ssq respectively.  The rou‐
       tine makes only one pass through the vector X.

ARGUMENTS
       N       (input) INTEGER
	       The number of elements to be used from the vector X.

       X       (input) COMPLEX array, dimension (N)
	       The vector x as described above.	 x( i )	 = X( 1	 +  (  i  -  1
	       )*INCX ), 1 <= i <= n.

       INCX    (input) INTEGER
	       The  increment between successive values of the vector X.  INCX
	       > 0.

       SCALE   (input/output) REAL
	       On entry, the value  scale  in the equation  above.   On	 exit,
	       SCALE is overwritten with the value  scl .

       SUMSQ   (input/output) REAL
	       On  entry,  the	value  sumsq  in the equation above.  On exit,
	       SUMSQ is overwritten with the value  ssq .
