Create a simple nearest-neighbor program using MATLAB. It should input a training set of data in m+l columns; one column should contain the population identifier 1, ..., k and the others contain the input vectors that can have length m. Along with this training set, also input another m column matrix representing the classification set. The output should contain n, m, k and the classifications for the input set.
