I have developed new method of fuzzy defuzzification. How to generate output surface for the proposed method? I want to comparison of proposed method with existing methods SOM, LOM, MOM, centroid and bisector in the form of output surface.
e.g.
or
surfview(fis)
In these methods, no option to select defuzzification method. Only inputs and output can be set. How to plot surface for different defuzzificztion methods?
Any other method for comparison? How to compute performance index for defuzzication method?
Please guide me.

Good to hear that a new defuzzification method is developed. To make the comparison meaningful, you must choose and compute the performance index for each method and to determine the method that delivers the best result in certain circumstances.

If you want to create a Custom Defuzzification Function, then read the information on this link:

Can you generate the surface in the Fuzzy Logic Designer app?
What command did you use to integrate the Custom defuzzification function into the FIS when generating the Mamdani fuzzy inference system?
