I have a problem in which I have to define a fuzzy membership function with variable x(1) x(2) like below. For these variables I have to generate random number between 1 and 5. x(1)<x(2). What will be code for that?

Set a constraint on so that .

fis = sugfis;

%% Random integer generator
n1  = 3;
n2  = 5 - n1;
x1  = randi(n1, 1);
x2  = randi(n2, 1) + x1;    % ensures x1 < x2

%% Fuzzy Input 1
fis = addInput(fis, [-1 +5], 'Name', 'x');
fis = addMF(fis, 'x', 'trimf', [0 x1 x2], 'Name', 'P');

%% Plot membership functions for input 1
plotmf(fis, 'input', 1), grid on, title('MFs for x')
