Is there any way to determne the number of support vectors while using classifier app?

I am using MATLAB classifer app and in that particularly classifier app. I need to compare the time complexity of SVM with corresponding ANN? In SVM the testing time complexity is O(kn), where k=number of support vectors and n=datasamples. For this I need k or number of support vectors.

Can someone guide on this please.

Thanks

Hi Krishna,

You can use the supportVectors propertt from the classificationSVM class to get the number of support vectors.

"Support vectors in the trained classifier, specified as an s-by-p numeric matrix. s is the number of support vectors in the trained classifier, sum(Mdl.IsSupportVector), and p is the number of predictor variables in the predictor data."

Hope it helps!
