end
svmStruct = fitcsvm(xdata,group,'OptimizeHyperparameters','auto','HyperparameterOptimizationOptions',struct('showplot',true));
% Testing
save svm svmStruct
load svm
for ii = 1:size(F1,1)
species = ClassificationSVM(svmStruct,F1(ii,:));
disp([ group{ii,1} ' = ' species]);
end
for ii = 1:size(F2,1)
species = ClassificationSVM(svmStruct,F2(ii,:));
disp([ group{ii+size(F1,1),1} ' = ' species]);
end
%%%%%%%%%%%%%%%
It runs for some time and gives error on classificationSVM.
Here Xdata is a 8x4 double. error says X should be a double or a single matrix. How to solve it and the other errors?
