IFitik [fi:tik] yinkqubo yokusetyenzwa kwedatha kunye ne-nonlinear ukulinganisa igophe.

Isetyenziswa ikakhulu

• nge izazinzulu abahlalutya idatha kwi-powder diffraction, chromatography, photoluminescence kunye ne-photoelectron spectroscopy, i-infrared kunye ne-Raman spectroscopy, kunye nezinye iindlela zokuvavanya,

• ukulinganisa iincopho - imisebenzi emise okwentsimbi (iGaussian, iLorentzian, iVoigt, iPearson VII, iGaussian ene-bifurcated, i-EMG, iDoniach-Sunjic, njl.),
