This is a matlab built in function called knnclassify, which is primarily used to identify the nearest neighbour of a data in matrix.

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.

The knnclassify () function uses the k-nearest neighbours classification algorithm to perform classification. The crossvalind () function is a separate one to divide a data set in to folds to perform cross-validation. Both are part of the Bioinformatics toolbox. A way to find out if the function is available in Matlab is typing which knnclassify. The output will be the route where the function resides or 'knnclassify' not found.

Distance metric used: Euclidean distance. Usage: [neighbors distances] Idx = knnsearch (X,Y) finds the nearest neighbor in X for each query point in Y and returns the indices of the nearest neighbors in Idx, a column vector. 2020-04-22 tl;dr: You can do it but you'll have to modify the knnclassify source if you want to do this.
