My own implementation of kMeans Machine Learning algorithm in Matlab
function[r,l] = kmyself(dataSet, k)
% Determine the size of dataSet
[nRow, nCol] = size(dataSet);
% Empty array for cluster assesment
clusterAssment = zeros(nRow,2);
% Setup centroid and choose on to start of with
centroids = zeros(k,nCol);
