The program was written to handle the numerical integration of initial value problems in which the frequency content of the variables differ considerably among themselves. In order to save computer time each variable is integrated with its own step-size so that the derivatives of the slowly changing variables are calculated less frequently than the derivatives of the rapidly changing variables. A second order Runge-Kutta method is used since high accuracy is not required. Author
