Hi,

As per my understanding, you want to know the default value of 'KernelFunction' in the 'fitcsvm()' function. It's as follows:-

Gaussian or Radial Basis Function (RBF) kernel, the default for one-class learning
Linear kernel, the default for two-class learning

The above information is also present in the documentation. See the table under 'KernelFunction' in 'SVM Options' section.

You can also access the 'KernelFunction' value of your model as follows: -

SVMModel = fitcsvm(x,y);
SVMModel.KernelParameters.Function
