... C(I, I+k): there are k ways to break up and multiply subsequent lower sub-chains: [M(i).M(I+1).M(I+2)…M(I+p)]. [M(I+p+1).M(I+p+2)…M(I+k)], for k values of p, I <= p <= I+k-1. The optimal cost for each of these two sub-chains are presumed to be correctly known as C(I,p) and C(p+1,I+k) by the hypothes ...

Why study matrix groups?
... • The shape of the universe might be a quotient of a certain matrix group, Sp(1), as recently proposed by Jeff Weeks (see Section 8.6). Weeks writes, “Matrix groups model possible shapes for the universe. Conceptually one thinks of the universe as a single multi-connected space, but when cosmologists ...

... These methods of referring to elements can be used to modify elements and in some cases to delete them. To delete element(s), the empty vector [] is assigned. This example creates a vector, modifies a value in it, and then deletes two elements: >> newvec = [22 5 9 11 54]; >> newvec(4) = 49 newvec = ...

Non-negative matrix factorization
NMF redirects here. For the bridge convention, see new minor forcing.Non-negative matrix factorization (NMF), also non-negative matrix approximation is a group of algorithms in multivariate analysis and linear algebra where a matrix V is factorized into (usually) two matrices W and H, with the property that all three matrices have no negative elements. This non-negativity makes the resulting matrices easier to inspect. Also, in applications such as processing of audio spectrograms non-negativity is inherent to the data being considered. Since the problem is not exactly solvable in general, it is commonly approximated numerically.NMF finds applications in such fields as computer vision, document clustering, chemometrics, audio signal processing and recommender systems.
