... eigenvalue. With regards to the latter case, since our vector p (0) is real, the coefficients ck and ck´ must be complex conjugates of each other when the corresponding e k and e k´ are complex conjugates also. I need to explain why e 1 has the factor 1 in front. This requires a bit of a digression: ...

... There is a canonical form for the row space of a matrix A, namely, its reduced echelon form REF(A). This m×n matrix is row equivalent to A and so has the same row space as A. It has the following properties: (a) The non-zero rows precede the zero rows; (b) The first non-zero entry in a non-zero row ...

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.
