Hello
I would like to ask about how to find the valure of Linear, Gaussian, Poly = 2, Poly = 3 for dataset of iris
I used the code bellow it runs without problem but I don't know how to calculate the value of them
t = templateSVM('Standardize',true,'BoxConstraint',100,'KernelFunction','linear','KernelScale','auto');
Mdl = fitcecoc(dataTrain(:,2:4),dataTrain.Species,'Learners',t);
Predictions_SVM_Linear = predict(Mdl,dataTest(:,2:4));
figure;
C_SVM_Linear = confusionmat(dataTest.Species,Predictions_SVM_Linear);
cm_SVM_Linear = confusionchart(C_SVM_Linear,{'Iris-setosa','Iris-versicolor','Iris-virginia'});
cm_SVM_Linear.Title = 'Iris Classification Using Linear SVM';
cm_SVM_Linear.RowSummary = 'row-normalized';
cm_SVM_Linear.ColumnSummary = 'column-normalized';

Hi Baraah,
From your question I understand that you want to use Linear, Gaussian and Polynomial Kernel functions in templateSVM function. You can use the following name, value pairs for these:
For further information on the Kernel Functions, please refer to the below documentation:
Thanks
