What Is Fuzzy Logic?

2 Tutorial
The fis.c file contains all the necessary functions to perform the fuzzy
inference process:
• This file provides the 11 Fuzzy Logic Toolbox membership functions with
their default settings.
• You can add a new membership function or new reasoning mechanism
by updating the fis.c file.
The fismain executable code, generated after compiling the source codes,
reads an input data file and a FIS structure file to simulate the output. The
syntax for calling fismain is similar to its MEX-file counterpart evalfis,
except that all matrices are replaced with files. To learn more about evalfis,
see the evalfis function reference page.
Example — Using the Fuzzy Inference Engine on
Windows Platforms
This example demonstrates how to simulate a fuzzy inference system on a
Windows ® platform using the stand-alone fuzzy inference engine. In this
example, you use the LCC C compiler shipped with MATLAB to compile the
fuzzy inference engine source codes.
1 Open a DOS Command Window and change the directory to
matlabroot\toolbox\fuzzy\fuzzy.
Tip You can find the root directory of your MATLAB installation by typing
matlabroot at the MATLAB command prompt.
2 In the DOS Command Window, type the following command:
lcc -c fismain.c
This command creates the fismain.obj object file in the
matlabroot\toolbox\fuzzy\fuzzy directory.
