DRSCL(3F)							     DRSCL(3F)

NAME
     DRSCL - multiplie an n-element real vector x by the real scalar 1/a

SYNOPSIS
     SUBROUTINE DRSCL( N, SA, SX, INCX )

	 INTEGER       INCX, N

	 DOUBLE	       PRECISION SA

	 DOUBLE	       PRECISION SX( * )

PURPOSE
     DRSCL multiplies an n-element real vector x by the real scalar 1/a.  This
     is done without overflow or underflow as long as
     the final result x/a does not overflow or underflow.

ARGUMENTS
     N	     (input) INTEGER
	     The number of components of the vector x.

     SA	     (input) DOUBLE PRECISION
	     The scalar a which is used to divide each component of x.	SA
	     must be >= 0, or the subroutine will divide by zero.

     SX	     (input/output) DOUBLE PRECISION array, dimension
	     (1+(N-1)*abs(INCX)) The n-element vector x.

     INCX    (input) INTEGER
	     The increment between successive values of the vector SX.	> 0:
	     SX(1) = X(1) and SX(1+(i-1)*INCX) = x(i),	   1< i<= n
