Fuzzy Logic Toolbox

Importing and Exporting from the GUI Tools

When you save a fuzzy system to disk, you're saving an ASCII text FIS file representation of that system with the file suffix .fis. This text file can be edited and modified and is simple to understand. When you save your fuzzy system to the MATLAB workspace, you're creating a variable (whose name you choose) that will act as a MATLAB structure for the FIS system. FIS files and FIS structures represent the same system.

Note    If you do not save your FIS to your disk, but only save it to the MATLAB workspace, you will not be able to recover it for use in a new MATLAB session.
