Hello! I have to graph a problem in Nebulous Logic with Matlab. I am rusty on my commands (never used Matlab before, so i'm not sure which one command to use. I am trying to make a function f(x,y)=-(x-10)^2-(y-10)^2. I need consideer a interval of [-10,10] and construct five fuzzy sets (C1,C2,C3,C4,C5) for eachone. Can somebody give-me a help ? i'm dying trying here T-T I need to use the fuzzy logic toolbox to solve this problem

I have no idea what a ‘cloud set’ is, although creating the function (here as an anonymous funciton) is straightforward:
f = @(x,y) -(x-10).^2 -(y-10).^2;
[X,Y] = meshgrid(-10:10);
figure(1)
meshc(X, Y, f(X,Y))
grid on
See the documentation on Function Basics (link) for the details on creating and using functions.
I added the plot for fun, and to demonstrate how to call the function.

Hello! Thanks for help. The "cloud set" is fuzzy set, sorry for bad translation

My pleasure!
Translation is not the problem. I suspected it is a ‘fuzzy set’ or something probabalistic, not that I am able to help with it just now.
MATLAB has a Fuzzy Logic Toolbox that I have but have not explored recently. Its functions could help you, and they should be compatible with other MATLAB code (such as your function).
