I am working in the Fuzzy Interface System. I have fuzzified the inputs and outputs and I have also framed fuzzy rules. I wish to know how defuzzification can be done in the Fuzzy logic Toolbox....
thanks...

I have a table with a sample of inputs and I want to see the deffuzification value for all. ¿How can I do this?

If you are using the Fuzzy Inference System editor, you can choose in the main GUI one of the defuzzication methods. The input for the defuzzification process is a fuzzy set. Actually, its the aggregate output fuzzy set which must be defuzzified in order to resolve a single value from the set.
The Fuzzy Logic Toolbox includes 5 defuzzification methods, from which the centroid calculation (which returns the center of area under the curve) is the most popular. The other methods are bisector, mom (mean value of maximum -the average of the maximum value of the output set-), som (smallest of maximum) and lom (largest of maximum).
I recommend you take a look at the following videos to see how the complete process is made:
