category "Education" was added to fityk.added access to symmetric errors from scripts (e.g.define Foo(alpha) = alpha * eta * (eta / tanh(eta) - ln (2*sinh(eta))) where eta = 2*pi/alpha * sin(theta/2), theta=x*pi/180 define supports variable substitution with "define.Peak fitting methods (moving window peak fitting, Fityk) are highly dependent on knowing the number of peaks. A new option `refresh-period` was added to control refreshing during fitting. The generation of false peaks is also a problem. GUI: On Linux fitting was very slow, this was fixed. And also, some kind of pretty output for the function which is found, like a LaTeX or MathML equation I think most of the issues Im having are down to me not.manual was converted from DocBook to reStructuredText.Fityk 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 What's New in This Release: To report a problem with the web site, e-mail debian-For other contact information, see the Debian contact page. Fityk also supports user-defined functions. It knows common bell-shaped functions (Gaussian, Lorentzian, Pearson 7, Voigt, Pseudo-Voigt) and. It supports data visualization, separation of overlapping peaks, and least squares fitting using standard Levenberg-Marquardt algorithm, a genetic algorithm, or Nelder-Mead simplex method. In case you are not familiar with the term weighted sum of squared residuals or you are. Fityk knows about common peak-shaped functions (Gaussian, Lorentzian, Voigt, Pearson VII, bifurcated Gaussian, EMG, Doniach-Sunjic, etc.) and polynomials. Fityk is nonlinear curve-fitting and data analysis software. Fityk is a program for nonlinear fitting of analytical functions. ![]() Fityk is reportedly used in crystallography, chromatography, photoluminescence and photoelectron spectroscopy, infrared and Raman spectroscopy, to name but a few. ![]() If you do prefer another programming language, Fityk library has C and C++ API, and comes with SWIG-based bindings for Python, Ruby, Perl and Java. If you have any questions about it, feel free to ask. This release also contains a few minor bug fixes and changed Data > Load File dialog. The previous 1.0.x releases have been reported to not work on OS X 10.5. There are also people using it to remove the baseline from data, or to display data only. You may also see the a sample distributed with the program. Announcing Fityk 1.0.2 - new version of peak fitting program. Fityk is a program for nonlinear fitting of analytical functions (especially peak-shaped) to data (usually experimental data).
