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
