Passing computations from ODE45

  1. Jun 27, 2007 #1
    Does anyone know a trick to pass variables computed in the user defined function called by ODE45 in MATLAB?

    For example, imagine you have the following code:

    [t,y] = ode45('DiffEQ',dt,Initial,options);

    function dy = DiffEQ(t,y)
    Fc = y(1)*y(2);
    dy(1) = y(2);
    dy(2) = -k*y(1)-c*y(2)+Fc;

    How can we pass Fc as an output? I don't want to re-compute Fc with the solutions. Thanks for any tips.

    Save it in a file or embed the code in a bigger one. Is not very consuming to do an ode45.
