am running the following code in matlab R2023b but it keeps returning the following error message:
Error using genfis
Invalid option sets.
Error in CreateInitialFIS (line 31)
fis = genfis(x, t, options);
Error in main (line 24)
fis=CreateInitialFIS(data,10);
The CreateInitialFIS.m code is:
function fis = CreateInitialFIS(data,nCluster)
if ~exist('nCluster', 'var')
nCluster = 'auto';
end
x = data.TrainInputs;
t = data.TrainTargets;
options = fcmOptions(...
NumClusters=nCluster,...
MaxNumIteration=100,...
MinImprovement=1e-5,...
Display=false);
% Create the FIS
fis = genfis(x, t, options);
end
The main.m code is:
%% Load Data
data=LoadData();
%% Generate Basic FIS
fis=CreateInitialFIS(data,10);
%% Train Using PSO
fis=TrainAnfisUsingPSO(fis,data);
%% Results
% Train Data
TrainOutputs=evalfis(data.TrainInputs,fis);
PlotResults(data.TrainTargets,TrainOutputs,'Train Data');
% Test Data
TestOutputs=evalfis(data.TestInputs,fis);
PlotResults(data.TestTargets,TestOutputs,'Test Data');

Hi @Ahmad
The error is due to the incorrect usage of the option set. The option set for the genfis() function should be genfisOptions(), while fcmOptions() is the option set for the fcm() function.
%% Load Data
data = rand(100, 5);
%% Generate Basic FIS
fis = CreateInitialFIS(data, 10)
function fis = CreateInitialFIS(data,nCluster)
if ~exist('nCluster', 'var')
nCluster = 'auto';
end
x = data(:,1:4);
t = data(:,5);
% options = fcmOptions(...
% NumClusters=nCluster,...
% MaxNumIteration=100,...
% MinImprovement=1e-5,...
% Verbose=false);
options = genfisOptions('FCMClustering', ...
NumClusters=nCluster, ...
MaxNumIteration=100, ...
MinImprovement=1e-5, ...
Verbose=false);
% Create the FIS
fis = genfis(x, t, options);
end

The "Display" option should be "Verbose" according to the documentation for FCM clustering options.
