Hi,
Can anyone please explain how to input custom sigma value for gaussian kernel while using fitcsvm function for SVM classifier. I am using rbf as the kernel function, but i want to manipulate the sigma value for the gaussian kernel instead of using the default sigma value. I tried using kernel scale with different inputs, but i think it doesn't change the sigma value. Any help would be greatly appreciated. Thanks!
