Sugeno_type ANFIS linear Parameters extraction

I used a sugeno-type ANFIS model for prediction. Pls how do I get the linear parameters. What I mean is the linear parameters of the consequent part (output) that is f=p1x+p2y+r I want to know the values of p1,p2 and r

Thanks

to disply rules use: showrule(fis,'RuleIndex',ruleIndex) to display parameters of this rule use: fis.output.mf(ruleIndex).params
