You use the more modern fitcknn, which is good, but you then pass the resulting model to the older knnclassify as if the model is training data. To classify your test data these days you should be using predict() on the model returned by fitcknn.

Are you trying to run the script from inside the ZIP-file, without extracting it? That won't work. Extract the files to a directory, make the files in that directory accessible to MATLAB (making it your current directory or adding it to the MATLAB path), and then you should be able to run the script.

Description class = classify (sample,training,group) classifies each row of the data in sample into one of the groups in training. sample and training must be matrices with the same number of columns. group is a grouping variable for training.

ClassificationKNN is a nearest-neighbor classification model in which you can alter both the distance metric and the number of nearest neighbors. Because a ClassificationKNN classifier stores training data, you can use the model to compute resubstitution predictions. Alternatively, use the model to classify new observations using the predict method. 2013-03-15 I am currently working on matlab and I am new to it.
