Error in Evalfis

??? Error using ==> evalfismex Illegal parameters in fisGaussianMF() --> sigma = 0

Error in ==> evalfis at 84 [output,IRR,ORR,ARR] = evalfismex(input, fis, numofpoints);

Error in ==> myfuzz1 at 28 z(i,j)=evalfis([p1 p2 p3 p4 p5 p6 p7 p8 p9],t);

can anybody tell what is the meaning of this error and how can i solve it

I would appreciate so much if you tell me how you solved this problem. I have this problem too.

I had this problem also! It was origniated because my training data was beeing generated incorectely. After I fixed it, I had no more problems.

My guess is that you somehow defined a Gaussian membership function with sigma set to 0. Here is the doc page explaining what Gaussian membership function is and what sigma is.

HTH.
