train_data=load('E:\sample_feature.txt'); train_label=load('E:\train_label.txt'); test_data=load('E:\features.txt'); k=knnclassify(test_data,train_data,train_label,3,'cosine','random');
the train_label is like this :
1 1 2 2 3 3
and the classified result is :
k = 3 3 3 3 2 3 3 1 3 3 3 2 2 3 1 3 3 3 3 3 3 3 3 3 3 3 3 3 3 1 3 3 3 3 3 3 3 3 3 3 2 3 3 1 3 3 3 1 3 1 3 3 1 3 1 2 3 3 3 1 2 1 3 2 1 3 2 1 3 2 2 3
