Part IX (§45- 47) Factorization
The proof of the uniquenss of such factorization is exactly same as that of theorem 23 20 I leave it as an exercise The proof is complete Remark 1 Suppose F is a field F (a) We proved that the polynomial ring F[x]is a PID (b) We also proved F[x]is a UFD, independently The same follows from the above theorem

Notes on Householder QR Factorization
LRis the QR factorization of A The second fundamental insight will be that the desired unitary transformations fH 0;:::;H n 1gcan be computed and applied cheaply 2 Householder Transformations (Re ectors) 2 1 The general case In this section we discuss Householder transformations, also referred to as re ectors 1
Lecture 13: Complex Eigenvalues & Factorization
In general, if a matrix A has complex eigenvalues, it may be similar to a block-diagonal matrix B, i e , there exists an invertible matrix P such that AP =PB; where B has the

4 2 Gaussian Elimination and LU-Factorization Let A beann⇥n matrix, let b 2 Rn beann-dimensional vector and assume that A is invertible Our goal is to solve the system Ax = b SinceA is assumed to be invertible, we know that this system has a unique solution, x = A1b Experience shows that two counter-intuitive facts are re-vealed:
Solution 1 - University of Illinois at Urbana–Champaign
Problem 1 2 (Exercise 4 1 in Koller/Friedman) In this problem, we will show by example that the distribution of a graphical model need not have a factorization of the form in the Hammersley-Cli ord Theorem if the distribution is not strictly positive
