Curve Fitting Downloads

FindGraph is a curve fitting and digitizing tool for engineers, scientists and graduate students. Convert plots back to X,Y data from any published report for later processing and manipulations. The program offers 12 generic fits, including Linear Regression, Logistic Functions, Fourier approximation, Neural Networks, B-splines curves, cycles extraction, SSA forecasting, and plus a library of over 300 industry-specific formulas.

DataFit is a tool used to perform nonlinear regression (curve fitting), statistical analysis & data plotting. Fit equations with up to 100 parameters to data with up to 20 independent variables. Define your own equations or choose from over 600 pre-defined equations. Results include customizable 2D/3D plots, as well as detailed fit information. Export code in BASIC or C to use an equation in a user written program. Easy to learn and use.

Low cost 2D function plotting software. Use up to 8 functions with cascades. Displays 2 simultaneous plots with cursors positions and deltas. File load, save, and print. Input point overlays for curve fitting. Trig, Ln, Log functions supported.

Curve Pilot designed for teaching the basics of color corrections of images created by a digital camera or scanner. Simply indicate which color you want to get as a result of color correction and Curve Pilot will automatically calculate the values for curves that allow you to achieve the goal. It will show the curves on the screen and perform color correction.

LAB Fit is a software for Windows developed for treatment and analysis of experimental data. At LABFit you are able to: 1) Treat similar data; 2) Treat non-similar data; 3) Determine propagated error; 4) Plot 2D and 3D graphs; 5) Execute math calculations (system of equations, roots of function, etc); 6) Curve Fit (almost 500 functions at the library, with 1 and 2 independent variables, functions finder, rejection of data).

NLREG performs nonlinear regression and curve fitting. NLREG fits a mathematical function whose form you specify to a set of data values. Virtually any type of function can be fitted. NLREG includes a programming language similar to C that you use for describing the function to be fitted. Two dimensional line and three dimensional surface plots can be generated.

Color Fitting helps you create color schemes for web and graphic design, slide shows and software interfaces, digital pictures and animations, DIY and stage decoration, clothing and fashion accessories, and anywhere where colors are used. You can spot good color combinations when you see them or a beautiful color when you see it, so there’s no better way to create color schemes than to free your mind to appreciate colors as they are in a contex

ImageDIG consists of three integrated modules which allow the user to convert 2D flat images into 3D (x,y,z) data or if a graph, convert the graph in image form into 2 dimensional numerical data. The third module is a full analysis plotting utility where the user can import either the 2D or 3D data saved above or import any number of columns of data from a file. The data can then be analyzed using several statistical functions and plotted.

A data analysis and 2D plot package. Produce XY plots, bar charts and pie charts of multicolumn datasets loaded from file or pasted from other applications. Allows users to create their own layouts with multiple axis per plot and plots per page then save as templates for easy re-use. Data manipulation includes standard equations and functions, integration and differentiation, curve-fitting including goodness-of-fit indicators. All analysis is r..

a powerful, easy-to-use, equation plotter with numerical and calculus features. Graph Cartesian functions, relations, and inequalities, plus polar, parametric, and ordinary differential equations. Numerically solve and graphically display tangent lines and integrals. Find critical points, solutions to equations, and intersections between Cartesian functions. For students and teachers from high-school algebra through college calculus.

DPlot is a general purpose graphing program designed for scientists, engineers, and students. It features multiple scaling types, including linear, logarithmic, and probability scales, as well as several special purpose plots: tripartite grids (shock spectra), grain size distribution plots, polar plots, contour plots of 3D data, and box-and-whisker plots and dot graphs of one or more 1D samples. Manipulation/analysis functions include FFT, filt..

CurvFit (tm) is a curve fitting program 4 Windows 9x. Lorentzian, Sine, Exponential and Power series are available models to match your data. A Lorentzian series is highly recommended for real data especially for multiple peaked/valleys data. CurvFit is an example of Fortran Calculus programming... ie. minutes to solve, days or years to understand solution and what it implies (e.g. wrong model, sampling rate error). See comments in EX*.?

Powerful but easy-to-use graphing, curve fitting and calculating software. Graphs Cartesian, polar and parametric functions, graphs of tables, implicit functions, inequalities and slope fields. Up to 100 graphs in one window. Calculus features: regression analysis, intersections, derivatives, tangents, normals and more. The program has printing capabilities, multi-document interface, customizable toolbars.
