From: rams on 25 Mar 2010 10:46 I am not able to use lsqnonlin or lsqcurvefit functions in matlab installed on my computer. This is possibly due to unavailability of optimization toolbox. Are there any functions similar to these that i can use.

To answer this, we need detailed information about the fitting problem you are trying to solve. Best wishes Torsten.

This is possibly due to unavailability of optimization toolbox. Are there any functions similar to these that i can use. It is "possibly" due to that? You either have that toolbox or you do not. It is simple to verify. It is not a fuzzy question. Look on the file exchange. Or, use fminsearch. You will need to think about how to formulate the sum of squares objective function then. John |
