03 Oct 2014 Peak Fitter Command-line peak fitter for time-series signals. Version 5.7, September, 2014 Author: Tom O'Haver

Thanks, Ismael. Both the command-line peakfit.m function and its interactive cousin ipf.m are described on http://terpconnect.umd.edu/~toh/spectrum/InteractivePeakFitter.htm. There is no dead-trees publication. Thanks again.

Great! Thanks for testing it. I'll upload that version to the File Exchange.

On the suggestion by Hao Wang, I've created a new version of peakfit.m (version 5.7) that includes a minimum width constraint as the 13th input argument. Download from http://terpconnect.umd.edu/~toh/spectrum/beta/peakfit.m
See example 19 in this file for an example of this feature. The default, when not specified, is equal to the independent variable (x) increment. Feedback please.

Excellent idea, Hao Wang; I'll work on that.

Ali, I can work on that. What's the specifications of your peaks: shape, height ratio, x-positions, and widths? How much noise? Are both peaks important in your work, or only the smaller one?

Hi Tom, First of all many thanks for this peak fitter, I have been using it quite a lot and it worked perfectly. Indeed I'm finishing one article where I have used it to fit some Raman spectra and I'm wondering how I can cite it, any clues?

Tom, it works in my case. Thanks for your timely response and great work !

Thanks Tom. I will experiment on it and give you some feedback asap.
