I have 5 sets of data. The curve of each set of data has an exponential decay with 4 parameters. I want to find the relationship of the parameters and obtain a global function.
How can I do it? Thanks!

The lsqcurvefit function can take matrix dependent variable data and fit them to matrix dependent variable data. (The nlinfit function will only allow single vector outputs.) You will probably have to experiment to get the result you want.
