i am using fuzzy inference system for stock trading analysis ,and I want my output to be fuzzy output(OUTPUT VARIABLE DESCRIPTOR VALUE) and not defuzzified( crisp) output which MATLAB provides?

I HAVE MULTIPLE INPUTS AND SINGLE OUTPUT SYSTEM. THE OUTPUT MEMBERSHIP FUNCTION IS TRIANGULAR MEMBERSHIP FUNCTION AND I HAVE ASSIGNED DESCRIPTORS TO IT. LIKE SELL , BUY OR HOLD.

NOW I WANT MY TRUNCATED OUTPUTS TO BE AGGREGATED. THEN I WANT TO FIND THE MAX OF THE FUZZY SET , AND THE DESCRIPTOR VALUE IN WHICH THAT MAX (HIGHEST MEMBERSHIP FUNCTION VALUE) COMES UNDER.

EXAMPLE : IF HIGHEST MEMBERSHIP FUNCTION VALUE IS 0.8 . THEN I WANT TO KNOW UNDER WHICH DESCRIPTOR THIS 0.8 COMES WHETHER ITS SELL , BUY OR HOLD.

IT MEANS I AM USING DEFUZZIFICATION METHOD " mean of maxima" WHERE I AM FINDING THE MAXIMA AND SENDING OUT THE DESCRIPTOR VALUE UNDER WHICH I FOUD OUT MY MAXIMUM MEMBERSHIP VALUE AS OUTPUT(buy ,sell OR hold) AND NOT THE VALUE PRESENT ON THE X-AXIS AS OUTPUT .

SO THAT MY OUT PUT IS EITHER BUY ,SELL OR HOLD .

PLEASE EARNESTLY WAITING FOR GENUINE SOLUTION.
