Testfitpeaks

Testfitpeaks

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).
