K-Medians
Description
We provide functions to provide robust clustering. Function gen_K enables to generate a sample of data following a contaminated Gaussian mixture. Functions Kmedians and Kmeans consists in a K-median and a K-means algorithms while Kplot enables to produce graph for both methods.
