Fuzzy Arithmetic

This is simple GUI which gives idea of fuzzy logic arithmetic operation

FA3(varargin)
function varargout = FA3(varargin)
% FA3 M-file for FA3.fig
%      FA3, by itself, creates a new FA3 or raises the existing
%      singleton*.
%
%      H = FA3 returns the handle to a new FA3 or the handle to
%      the existing singleton*.
%
%      FA3('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in FA3.M with the given input arguments.
%
%      FA3('Property','Value',...) creates a new FA3 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before FA3_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to FA3_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
