The solution is made using the matlab routine ode45.

Its arguments are

--- reference to the function odefun(t,y) which calculates the vector of derivatives dy/dt = yp(t,y)

--- the points in time at which you want to know the values of vector y

--- the initial values of vector y

The results of the integration are plotted in figure 101
