I am using this command: cl3 = fitcsvm (X,Y,'KernelFunction','rbf', 'Standardize',true,'BoxConstraint',2,'ClassNames', [-1,1]); and wanted to plot the SVM generated boundries for different sigma values. Where do you include the sigma values?

Webfitcsvm finds optimal values of BoxConstraint and KernelScale. Set the hyperparameter optimization options to use the cross-validation partition c and to choose the 'expected-improvement-plus' acquisition function for reproducibility. The default acquisition function depends on run time and, therefore, can give varying results.
