JPathfinder is the latest Java version of the software. It runs on any computer with an up-to-date version of Java (free). Some sample data files and a terms file are placed in a "jpf" directory for experimentation. This software is now very stable, but please report any problems or bugs. You also should download fresh copies before starting new projects to take advantage of any fixes that have been made.

Matlab version of Pathfinder (7.0)
The Matlab version requires Matlab version 2015a or later as well as the Statistics and Machine Learning Toolbox. The downloaded files include the required .m files and some sample data sets to exercise the software.

Download Matlab pf7.zip
Documentation is available in the MS Word file, "Pathfinder.doc" which will be found in the folder into which you extract the pathfinder files.

Extract the zipped files to a directory of your choosing, make that directory the current directory in Matlab, and enter "pathfinder" in the Matlab Command Window to start.

The "Help" button in the Pathfinder application will open the "Pathfinder.doc" file.
