           Fuzzy Inference Systems toolbox for MATLAB 
	        version 4.1, Personal Computer
----------------------------------------------------------------------
Fuzzy inference systems toolbox for MATLAB ,FISMAT, accommodates 
different arithmetic operators, fuzzification and defuzzification 
algorithm, implication relations, and different method of approximate
reasoning such as Compositional Rule of Inference (CRI) and Approximate
Analogical Reasoning Scheme based on Similarity Measure.

To have a quick review of FIS and become familiar with developed
functions, a demonstration file "fisdemo.m" is provided. Therefore
after retrieving the files it is recommended to go through different
part of demo. The demonstration includes fuzzy controller demo which
investigate three well-known examples in control systems. These are
truck backer-upper control, inverted pendulum system (cart-pole), and
temperature and humidity control of a bathroom. 

The programs have been tested on MATLAB version 4.1, Sun workstation.

To become familiar with terminology used for FIS and also the list of
references for each function, a postscript file "FISMATPC.ps" also
provided.

It is to be noted that FISMAT is a public domain program, therefore
no one is allowed to sell it or revise and re-distribute the programs
with his/her name. The permission for revision and re-distribution is
given subject to keep the header (s) of functions.

I am looking forward to hear your suggestion, comments or any possibly
errors.
