Difficulty in knnclassify function. Learn more about difficulty in knnclassify function MATLAB Nearest neighbor MATLAB code. K Nearest Neighbors - File Exchange - MATLAB Central, Program to find the k - nearest neighbors (kNN) within a set of points. 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. Alternatively, you can see what knnclassify is doing, then just pull out the relevant calls that pertain to just your case and place your custom histogram intersection method accordingly, create a new file and just run this file.
