DRSCL(3)                   MathKeisan LAPACK routine                  DRSCL(3)



NAME
       DRSCL - 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
