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.
!> 

Parameters

[in]	N	!> N is INTEGER !> The number of components of the vector x. !>
[in]	SA	!> SA is 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. !>
[in,out]	SX	!> SX is DOUBLE PRECISION array, dimension !> (1+(N-1)*abs(INCX)) !> The n-element vector x. !>
[in]	INCX	!> INCX is 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 !>
