load featurs_T
load featurs_S
load Group_Train
load Group_Test
Feat1 = pca(Feat1);
Feat2 = pca (Feat2);
%------------------------
result= classify(Feat1,Feat1,Group_Train1,'diaglinear');
Accuracy = mean(Group_Test1==result) * 100;
fprintf('Accuracy = %.2f\n', Accuracy);
fprintf('error rate = %.2f\n ', mean(result ~= Group_Test1 ) * 100);
why is pca decreasing the number of images and thus I get this error
while the Group and Training before using pca were equal
Feat1 95904x1031 double
Feat2 95904x108 double
Group_Train1 1x1032 double
Group_Test1 1x109 double
