By haying:

So I clone the format of two other algorithms and add the description and reference. https://github.com/haying/madlib/commit/41f353d6e4f8f375e36537cbd998d436e04d449a

Since there are not really any formula describing two other algorithms, I have not added any. Please let me know if anything I can help to improve it in the way you like.
