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
