I don't know the parameters in question. I did not understand what you said, I am trying to find a, b and c, all I know are the "responses", y1, y2 and y3. So, how'd you use ode45 to find the parameters a, b and c?
of course I could give a starting guess if necessary, or a typical solution, as they say!
Many thanks in advance!
