Purpose
Demo calls to the FITPEAKS function.
Synopsis
- [peakdef,fval,exitflag,output] = testfitpeaks(test)
Description
TESTFITPEAKS is a set of example calls to FITPEAKS. Editing this M-file provides some insight into how the peak fitting utilities can be used.
No input is required.
Optional Inputs
- test = calls different peak fitting examples.
- test = 1 fits a single Gaussian peak.
- test = 2 fits two Gaussian peaks.
- test = 3 fits a single Lorentzian peak.
- test = 4 fits two Lorentzian peaks.
- test = 5 fits a Gaussian and Lorentzian peak.
- test = 6 fits a single PVoigt2 peak.
- test = 7 fits a Gaussian and a PVoigt2 peak.
- test = 8 fits a Gaussian and a PVoigt1 peak.
- test = 9 fits a single PVoigt1 peak.
Outputs
- peakdef = The input peak structure (peakdef) with parameters changed to correspond to the best fit values.
- fval = Scalar value of the objective function evaluated at termination of FITPEAKS.
- exitflag = Describes the exit condition (see LMOPTIMIZEBND).
- out = Structure array with information on the optimization/fitting (see LMOPTIMIZEBND).
