Getting the Defuzzified surface function in Fuzzy Logic ToolBox

Is there a way to get the Defuzzified surface function as a z=ax^m+by^n+c format in fuzzy logic toolbox?

I can do everything else including getting the crisp output value for x and y inputs. Bu I need the total defuzzified function as a whole.

I know there will be different function for different range of x and y.

hello please how did you do your fuzzification i am having issues with that and i want to interface matlab with java

why do you need closed-form expression for the surface function? Is it for speeding up calculations?

There is no way to get a closed -form expression, but you can approximate the surface with a look-up table if the goal is to speed up computation time.

The workflow for that is shown in this example .
