DRSCL(3)       LAPACK routine of NEC Numeric Library Collection       DRSCL(3)



NAME
       DRSCL

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



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)
                     N is INTEGER
                     The number of components of the vector x.

           SA        (input)
                     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.

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

           INCX      (input)
                     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
