A mostly MATLAB-compatible fuzzy logic toolkit for Octave. A complete function reference is located here: https://lmarkowsky.github.io/fuzzy-logic-toolkit/, and the official Octave documentation is here: https://www.octave.org/support
If the function reference and Octave documentation do not address your questions or if you have comments, contact me at lmarkov@users.sourceforge.net.

I'm sorry to hear that you had trouble installing the package. For Octave to install any package, the <package_name>.tar.gz file must be in the load path in order to be found. One way to make sure that the gzipped tar file is in the current directory is to use commands (such as pwd, cd, ls, and dir) directly at the Octave prompt. For more about Octave commands to change the current directory and to list the current directory's files, see the latest Octave documentation: https://docs.octave.org/latest/Current-Working-Directory.html -
I've used the Toolkit for some control projects and have reported on it in my blog: johnbakeree.blogspot.com/2015/01/octave-and-fuzzy-logic-for-paint-flow. I have used the Toolkit for only the Mamdani analysis and found it quite useful and easy to use, but quite slow on my ASUS notebook PC, probably because Octave is an interpreter language. However, I do find the Toolkit lacking in that it doesn't produce a LUT that I can use in my other programs such as LabWindows/CVI or C#. Back in January 2015 I was able to insert code into the gensurf function to get it to output the LUT in a file but subsequently I had trouble with my PC and I lost my code when I reinstalled Win7 and have not been able to regenerate it. :-( If LMarkowsky would provide the code for me, I would appreciate it very much. Anyhow, thanks LMarkowsky for providing such a useful toolkit. JohnReply from Octave Fuzzy Logic ToolkitPosted 2024-05-13
Thank you for your kind review. I'm always glad to hear that the toolkit has been useful. About providing the code -- the package is completely open source, and the gzipped tar file contains all of the code in its entirety. If you have the tar file, then look in the inst and inst/private directories. All of the code is written in the Octave programming language, with the extension .m.
