... (a) Show that SL(2, 3) has order 24 and has 4 Sylow 3-subgroups (You can probably do this by counting elements of order 3). (b) Show that if SL(2, 3) acts by conjugation on the set of Sylow 3-subgroups, then the kernel of this action is {I, −I} = Z(SL(2, 3)). Therefore there is an isomorphism of SL( ...

Math 2270 - Lecture 33 : Positive Definite Matrices
... I’ve already told you what a positive definite matrix is. A matrix is positive definite if it’s symmetric and all its eigenvalues are positive. The thing is, there are a lot of other equivalent ways to define a positive definite matrix. One equivalent definition can be derived using the fact that fo ...

... Of course, this is far from the only possible basis we could have found. Some people solved this problem by noticing right away that C(A) had to be all of R2 , because the first two columns were already linearly independent, and therefore saved themselves the trouble of row reducing (but we have to ...

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.
