The software package 'relax' is designed for the study of molecular dynamics through the analysis of experimental NMR data. Organic molecules, proteins, RNA, DNA, sugars, and other biomolecules are all supported. It supports exponential curve fitting for the calculation of the R1 and R2 relaxation rates, calculation of the NOE, reduced spectral density mapping, the Lipari and Szabo model-free analysis, study of domain motions via the N-state model and frame order dynamics theories using anisotropic NMR parameters such as RDCs and PCSs, the investigation of stereochemistry in dynamic ensembles, and the analysis of relaxation dispersion data.

QtiPlot is a user-friendly, platform independent data analysis and visualization application similar to the non-free Windows program Origin.

VStar is a multi-platform, easy-to-use variable star observation visualisation and analysis tool. Data can be read from a file or the AAVSO database, light curves and phase plots created, period analysis performed, and filters applied. Plugins can be developed, e.g. to make additional observation sources available.

TF Quant Finance is a high-performance library of quantitative finance components built on TensorFlow, aimed at research and production workloads. It implements pricing engines, risk measures, stochastic models, optimizers, and random number generators that are differentiable and vectorized for accelerators. Users can value options and fixed-income instruments, simulate paths, fit curves, and calibrate models while leveraging TensorFlow’s jit compilation and automatic differentiation. The...

A self-contained C library for Levenberg-Marquardt least-squares minimization and curve fitting. To minimize arbitrary user-provided functions, or to fit user-provided data. No need to provide derivatives. With application examples.

XmgFit is a wrapper for Xmgrace (*) allowing to use comfortable the non-linear curve fitting capability of Xmgrace from the command line. Therefore the capabilities are limited by xmgrace. Please refer to the xmgrace users guide for more details. It is also handy to incorporate in shell scripts. The -s or --scripty option returns all result values xmgrace provide in an EVALuable format to make them easy available in shell scripts

The repository has been moved to: https://github.com/wojdyr/fityk. Fityk is nonlinear curve-fitting and data analysis software. It is specialized in fitting peaks (bell-shaped functions like Gaussian, Loretzian, Pearson7, Voigt) to experimental data.

Helps compatibility with Vernier's Graphical Analysis and Logger Pro software. Includes a converter to extract important data out of Vernier .ga3 and .cmbl data files, and spreadsheet to analyze the data with tables, graphs, and curve fitting.

TablPlot for Linux. TablPlot is a easy to use little program that reads a number table and makes a Cartesian (XY) plot. Automatic (log)scaling, plot sizing, spline interpolation, curve fitting and PostScript output are included.

grafix: SGML-based scientific diagram editor, can do arbitrary user-defined transformations of input data, data interpolation by several methods, and curve fitting to arbitrary user-defined functions; generates PostScript (EPS) output

Scientific data acquisition and visualization package with easy-to-learn script language and powerful widgets (including 2D graphs with nonlinear curve fitting). Support for Serial ports, GPIB devices and Labcards, localy or remotely using RPC over TCP
