Thanks, both of you. I actually had tried something similar to what you both suggested, but it didn't seem like the function was converging to a solution, so I (incorrectly!) assumed the problem must be with the ODE nature of my system.
It might be, sort of. You will probably have to have a good guess of the parameters. The functions generated by many ODEs tend to be less suitable for fitting than other functions of interest. You may encounter many local optima. It would be worthwhile to do a bit of brute force searching through your parameter space to get a good starting point or use a global optimizer. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
