1. Download the data file. The last value in each row contains the target label for that row, and the remaining values are the features. Split the data into 10 approximately equally-sized "folds".

Hints:
For 2:
X = rescale(X, 0, 1);
For 4
K = 1:2:15
for index = 1 : length(K)
thisk = K(index);
% Call knnsearch()
% Compute accuracy
for index2 = 1 : length(X)
accuracy(index) = ......whatever
end
end
plot(K, accuracy, 'b.', 'LineWidth', 2, 'MarkerSize', 20)
You can finish it if you look up knnsearch() and figure out what it does.
