Learn more about knnclassify Statistics and Machine Learning Toolbox 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. knnclassify has an optional fourth argument k which is the number of nearest neighbors. [1..25] and save result in matrix matlab. I want also to plot the result to see the variability of accuracy depending on the value of k. Please, help me to change this code and thanks in advance. how can I convert knnclassify to fitcknn.

Most MATLAB users understand variable definitions in th MATLAB: How to find distance matrix using knnclassify in matlab knn distance classification I work in image classication and I used two classifiers : svm et knn. the problem is that the knnclassify matlab function allows only return a list of labels test images (class) and I need to get out the distance matrix Error using knnclassify classifier. Learn more about knnclassify classification knnclassify Hi I am currently new at Matlab and I have been trying to classify data by using knnclassify, so far I understand the concept and the tutorial given by matlab. I wish now to classify a sample of data, say a set of co-ordinates and classify it against two or more training data sets, choosing one of the two training sets (classifying by matrix rather than row).

This calls knnclassify on MATLAB and organizes data from Virtual Motion Labs' Data Glove Lite. The goal of this project is to test the robustness of k-nearest-neighbor algorithm and discover how the training basis, the quantity of samples, and the relationship of finger flexibility and hand rotation affect the accuracy of gesture recognition. modifying results of knnclassify.
