# k-nearest-neighbors matlab

The above code takes a new point i.e [5 1.45] and finds the 10 closest value that is close to the new point, can anyone please show me a matlab algorithm with detail of what the knnsearch function does? is there any other way to do this??The basis of the K-Nearest Neighbour (KNN) algorithm is that Construct a k-nearest neighbor classifier for Fishers iris data, where k, the number of nearest neighbors in the predictors, is 5.You clicked a link that corresponds to this MATLAB command: Run the command by entering it in the MATLAB Command Window.
