You can fit multiple datasets together using common set of parameters. You can model zero-shift in your instrument or do more complicated refinement of the X scale. If you don t know how to handle your case, do not hesistate to ask on the users group 2 or contact the author. To download the latest version of the program or to contact the author visit 3. 43, (2010) ĥ Open Source Fityk is open-source (GPL2+ 6 ). If you are interested, please find the source code at GitHub 7. It uses a few open source projects: NLopt 8 for several optional fitting methods one of the fitting methods uses MPFIT 9 library (MINPACK-1 Least Squares Fitting Library in C), which includes software developed by the University of Chicago, as Operator of Argonne National Laboratory. xylib 10 library handles reading data files Lua 11 interpreter is embedded for scripting and a few popular libraries and tools that make programming much easier: wxwidgets (GUI), Boost (misc), zlib (compression), readline (CLI), SWIG (bindings), Catch (testing).

Use can configure what is displayed and how (through GUI Configure or context menu). The helper plot shows how well the model fits the data. You may have one, two or no helper plots (GUI Show). By default, the plot shows the difference between the data and the model. It can also show weighted or cumulative 3ħ difference, and a couple of other things. Warez is harming producers of the software.The helper plot is also handy for zooming with left and middle mouse buttons. You cannot find here any torrents or download links that would lead you to dangerous sites.įyxm.net does support free software, however we do not support warez or illegal downloads. Our experts on malware detection tested Fityk with various spyware and malware detection programs, including custom malware and spyware detection, and absolutelly no malware or spyware was found in Fityk.Īll software that you can find on our servers, including Fityk, is either freeware, shareware or open-source, some of the software packages are demo, trial or patch versions and if possible (public domain licence), we also host official full versions of software.īecause we want to be one of the fastest download sites on the web, we host all the software including Fityk on our servers. No infections have been found and downloading Fityk is completelly problem free because of that reason. Various leading antiviruses have been used to test Fityk, if it contains any viruses. It is checked for possible viruses and is proven to be 100% clean and safe. All software that you can find here is freely downloadable and legal.įityk installation package is prepared to be downloaded from our fast download servers. Our collection also doesn't contain any keygens, because keygen programs are being used in illegal ways which we do not support. There is no crack, serial number, hack or activation key for Fityk present here. Every software that you are able to download on our site is legal. You cannot download any crack or serial number for Fityk on this page. Fityk also supports user-defined functions.įityk offers intuitive graphical interface (and also command line interface), variouse optimization methods (standard Marquardt least-square algorithm, Genetic Algorithms, Nelder-Mead simplex), equality constraints, automation of common tasks with scripts There are also people using it to remove the baseline from data, or to display data only.įityk is reportedly used in crystallography, chromatography, photoluminescence and photoelectron spectroscopy, infrared and Raman spectroscopy, to name but a few.įityk knows about common peak-shaped functions (Gaussian, Lorentzian, Voigt, Pearson VII, bifurcated Gaussian, EMG, Doniach-Sunjic, etc.) and polynomials. Fityk is a program for nonlinear fitting of analytical functions (especially peak-shaped) to data (usually experimental data).
