pro Fit download page
Below are links to various pro Fit related files that are currently available to download, starting with the application itself.
The pro Fit application
The latest version of pro Fit is pro Fit 7. If you are interested in trying out pro Fit 7, just go ahead and download it: it will run in a trial mode until you purchase a registration code. Some features are limited when pro Fit is run in trial mode, but it is perfectly adequate for smaller tasks.
If for some reason you need to run older versions of pro Fit, they are also available in the table below. These older versions are only for users who have purchased a registration code for them, but trial versions are available here.
A list of differences between the various versions can be found on our release history page.
pro Fit plug-ins, other downloads
Building plug-ins (external modules) to expand pro Fit's capabilities.
- Xcode projects and files (172 kB)
Sample code for building plug-ins (external modules) using Xcode 10.
Some pre-built plug-ins (external modules)
- ImageLoader (52 kB)
This plug-in (for pro Fit 6.0) is an image to number converter. It converts images to a table, each cell representing the value of one pixel.
Author: Chris Lee
- CirclePlot (81 kB)
A plug-in for plotting data as circles of variable radius. The plug-in is not only very useful, but it shows some interesting programming techniques.
Author: Chris Lee
- HDF Import Module 1.0 (260 kB)
This is a plug-in for reading "scientific datasets" from HDF files. HDF is well known standard for storing data.
- Smith Chart Module 1.0.1 (8 kB)
A Smith Chart is essentially a polar plot of the voltage reflection coefficient typically encountered in electromagnetic transmission line problems. This plug-in will plot reflection coefficient data (i.e., S11 and S22 S-parameters), and/or normalized impeadance data, expressed in polar form (magnitude and phase).
Author: Mark Yannuzzi.
- ODE Module
A plug-in to solve systems of coupled differential equations. Up to 12 first order equations are supported. Solutions can be plotted as phase diagrams. Comes in a Universal version. A short summary documentation can be found here. Author: Dirk Fröhling.
- Mechanics examples with pro Fit
A description of the solutions of various mechanical problems using pro Fit. German only. Author: Dirk Fröhling.
- Plot3D 2.1.0 (136 kB)
The last version of the Plot3D plug-in. Plot3D is the predecessor of the plug-in "3DPlotterGL" that comes with the pro Fit package. While 3DPlotterGL is built on OpenGL, Plot3D is built on Apple's Quickdraw 3D technology. Plot3D is posted here for users who do not (or cannot) use OpenGL because they are running pro Fit on a legacy MacOS. All others should use 3DPlotterGL.
- Plot3D 2.1.0 and source files (367 kB)
The Plot3D plug-in together with its source-files.
- Bessel 1.0 (17 kB)
This is an implementation of the various Bessel functions. PowerMac version only.
- LNRelaxation(30 kB)
A function providing a Gaussian relaxation time distribution and the decay function resulting from that. It is an example of recursive programming and contains an implementation of a smart integration algorithm. Author: Christoph Baehr.
- MultipleGaussian (32 kB)
A function providing up to 10 Gaussian functions plus a background function. It is an example of the use of parameters as selectors and switches. MultiGauss includes a small helper program that helps handling its large number of parameters. Published: 20/6/96, Author: Christoph Baehr .
