27 Apr 2009	iPeak: Interactive Peak Detector (Version 1.1) Interactive peak detector function. Author: Tom O'Haver	Version 1.1 posted 25 Apr 2009 adds keypress command "L" which toggles ON and OFF peak labels in the upper panel (zoomed-in segment). Each peak in that segment is labeled with peak position, height, and width. The labels change in real-time as the peak detection parameters are modified.
17 Apr 2009	Peak finding and measurement (version 2) Function to locate and measure the positive peaks in noisy data sets. Author: Tom O'Haver	Latest version just uploaded corrects a bug in the FindPeakSlidersG script that caused a malfunction when individual peaks are viewed if the x-axis data series does not start with zero.
14 Apr 2009	Interactive Peak Fitter (Version 4.1) Keyboard operated peak fitting function for time-series signals. Author: Tom O'Haver	Version 4: April 2008: Added keypress function "x" to refine the fit by performing 10 trial fits with slightly different first guesses and take the one with the lowest fitting error. You can change the number of trials, "NumTrials", in line 69 (the default is 10)
28 Mar 2009	Interactive Peak Fitter (Version 4.1) Keyboard operated peak fitting function for time-series signals. Author: Tom O'Haver	This latest version (3.3) add two features: 1. It computes the model at 100 points regardless of number of data points, giving the graph a smoother appearance. 2. A new keypress function, "d", to print out x,y values of the current data segment.
27 Dec 2008	Interactive Peak Fitter, version 2.2 A peak fitting program for time-series signals. Author: Tom O'Haver	I've placed an updated version of this file at http://terpconnect.umd.edu/~toh/spectrum/ipf.m as of December 26, 2008. It removes the "Warning" command that was causing an error in Matlab 7, and it eliminates the warning message about integer indexes with the colon operator. Tom O'Haver

19 Aug 2009	Peak finding and measurement (version 2) Function to locate and measure the positive peaks in noisy data sets. Author: Tom O'Haver	Coen, Michael	And comment out line 372 of rtslid.m as well... :)
19 Aug 2009	Peak finding and measurement (version 2) Function to locate and measure the positive peaks in noisy data sets. Author: Tom O'Haver	Coen, Michael	Ah, commenting out line 337 of rtslid.m: "figure(params.fig);" eliminates crashes for later versions of Matlab...
19 Aug 2009	Peak finding and measurement (version 2) Function to locate and measure the positive peaks in noisy data sets. Author: Tom O'Haver	Coen, Michael	Very nifty idea but it crashes quickly in Matlab 2008b, 2009a, and 2009b. There are clearly some GUI incompatibilities.
