How to convert knnclassify to fitckkn

x=readtable("datatraining.xlsx");

latih=x;

group=latih(:,3);

latih = [latih(:,1) latih(:,2)];

for i = 1 : 80

y=readtable("datatesting.xlsx");

sampel = y;

test = [sampel(:,1) sampel(:,2)];

%sampel = [2.6136 0.1284 1.3017 -0.8089 0.0441 -0,2084];

hasil=knnclassify(test,latih,group);

end

nama = "hasil KNN.xlsx";

hasil = [sampel(:,1) sampel(:,2) sampel(:,3) hasil];

xlswrite(nama,hasil);
