Change the value of sigma using the fitcsvm function in Matlab

I wanted to know how to go about changing the value of sigma using the fitcsvm in Matlab.

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?

Thanks for your time and help.

Use KernelScale parameter to set g, f.e.:

cl3 = fitcsvm(X, Y, 'KernelFunction', 'rbf', 'KernelScale', 0.1, ...
             'Standardize', true, 'BoxConstraint', 2, 'ClassNames', [-1,1]);
