evalfismex是什么啊

aaa210727

我的程序运行起来总是出现如下错误：

??? Invalid FIS. PARAMS field of linear output MF has incorrect length.
Error in ==> evalfis at 84
[output,IRR,ORR,ARR] = evalfismex(input, fis, numofpoints);


我根本找不到这个函数。
源程序如下：
%Sugeno type fuzzy control for single inverted pendulum
close all;
P=[-10-10i;-10+10i];     %Stable pole point
F1=place(A1,B1,P)
