Update rules for the Non-negative Matrix Factorization. This follows a method described in the paper 'Algorithms for Non-negative Matrix Factorization' by D. D. Lee and H. S. Seung. This is a multiplicative rule that ensures that the Frobenius norm $ \sqrt{\sum_i \sum_j(V-WH)^2} $ is non-increasing between subsequent iterations. Both of the update rules for W and H are defined in this file.
