Smart Lorentz Gauss

What the package can do for you

This package provides functionalities to compute an n-dimensional mixed Lorentz-Gauss line shape, also called an n-dimensional Pseudo-Voigt function. Typically such functions occur in spectroscopic data originating from electro-magnetic radiation. The function can for example be used for fitting or deconvolution of such data.

The major API functionalities

  • class LorentzGauss

This example constructs a LorentzGauss shape with the given height, center, width, and Gaussian fraction.

LorentzGauss lg = new LorentzGauss.fromPars(height, [center], [width], [0.2]);

This example would compute the value of the above shape value at position x.

double val = lg.getValueAt(x]);
