   Functions/Subroutines
       subroutine srscl (N, SA, SX, INCX)
           SRSCL multiplies a vector by the reciprocal of a real scalar.

Function/Subroutine Documentation

   subroutine srscl (integer N, real SA, real, dimension( * ) SX, integer INCX)
       SRSCL multiplies a vector by the reciprocal of a real scalar.

       Purpose:

            SRSCL 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:
           N

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

           SA

                     SA is REAL
                     The scalar a which is used to divide each component of x.
                     SA must be >= 0, or the subroutine will divide by zero.

           SX

                     SX is REAL array, dimension
                                    (1+(N-1)*abs(INCX))
                     The n-element vector x.

           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
