Fw: Clustering::Distance.php

Hi! (again) Here's some code i've coded for measuring distances and similarities, a basic step in clustering of data (thanks Jesus). Not all clustering methods are working (???) but I'm working on it :-) Distance.php: A library for distance measuring. It includes a pear class, Clus_Distance which implements diverse methods as internal functions. I have tought about reasons not to make a parent class and derive child classes for each method, but please feel free to make any comments that you think might help to PEARIZE this code w/o harming efficience. example1.php: A simple example that reads from data file, and shows similarity matrices (upper triangular) for each method. swiss.txt: Some sample data. The last column is the class number of each item, as outputed from a k-means implementation (not in php), so we'll be living on R^6 and comparing these to ours. please review it, and make any comments you like!!
