MATLAB fuzzy logic toolbox facilitates the development of fuzzy-logic systems using:
IntroductionIntroduction
The tool can be used for building
• Fuzzy Expert Systems
• Adaptive Neuro-Fuzzy Inference Systems (ANFIS)
• graphical user interface (GUI) tools
• command line functionality

Golden rules for tipping:
1. IF the service is poor OR the food is rancid, THEN tip is cheap (5%).
2. IF the service is good, THEN tip is average (15%).
3. IF the service is excellent OR the food is delicious, THEN tip is generous (25%).
