I have a model, a system of Odes, defined by a set of parameters. I also have a number of raw experimental data sets. I want to find an optimal parameterisation, what is a method of doing so?

Does there exist functionality in matlab to score the fit of one data set to another? If so I can easily write an optimisation algorithm using fmincon.

Any help is greatly appreciated as I have not attempted something like this before.

In addition to that this might be a possible solution provided you have access to the system identification toolbox: Estimating Nonlinear Grey-Box Models
