LeyLa is a Matlab-based tool for analysing Raman spectra. The name is derived from two cities (Ljubljana and Leoben) where the idea for this program emerged.


  • Fitting spectra with analytical functions including errorbar estimates (Curve Fitting Tool)
  • Spline background correction
  • Spectra subtraction, shift, normalization, binning, etc.

Analytical functions used for fitting are defined in a separate file. This way new functions can be added easily.

Recognized file formats

  • Plain ASCII (two columns, no header)
