Fityk

Fityk is a super handy software that helps you fit data to nonlinear functions. It’s perfect for experimental data from different areas like chromatography, spectroscopy, and crystallography.

Easy to Use Software

The cool thing about Fityk is that it’s pretty simple to get started with. You don’t need a ton of experience or know-how with similar tools, but it does come packed with some complex features. So, while beginners might need to check out the docs first, seasoned users can really dig into its depth.

User-Friendly Interface

Don’t worry about getting lost—the Fityk interface is straightforward! You’ll find a toolbar that lets you quickly access the most used functions. There’s also a menu bar, a main plot area, and a handy right-side panel where you can tweak certain values.

Multiple Fitting Methods

When it comes to fitting methods, Fityk has got your back. You can choose from 'Levenberg – Marquardt', 'Nelder - Mead Simplex', or even the 'Genetic Algorithm'. Depending on what you're working on, you can switch between modes like 'Data Range', 'Add Peak', or 'Baseline'.

Advanced Features for Data Analysis

This tool also lets you run scripts and transform data points. Plus, there are tons of function options available—think Quadratic, Cubic, Gaussian, Lorentzian, EMG, Polyline, ExpDecay, Voigt, Spline—you name it! You can even create your own functions!

Power Diffraction Analysis

If you’re into power diffraction analysis using X-Ray or Neutron radiation (like Cu or Ag), Fityk is perfect for that too! It allows you to exclude inactive points during fitting operations and work with multiple datasets at once.

A Powerful Tool for Scientists

In short, Fityk is an efficient application designed for nonlinear data fitting based on experimental results from various scientific fields. Whether you're just starting out or looking to dive deeper into data analysis,Fityk wants to help!
