Posts | About Graph all the things analyzing all the things you forgot to wonder about 6 Matrix Decompositions Everyone* Should Know 2023-03-27 *everyone’s conjugate transpose The title is a joke, but was inspired by the 110-page tome What Every Programmer Should Know About Memory , which I think is not a joke? I’m going to try explaining these 6 useful matrix decompositions: Decompositions The first 4 (SVD, Eigen, Schur, PSD eigen) help with geometry and exponentiation. The last 2 (LU and Cholesky) help calculate determinants and solve for in systems of equations like . Scroll to the bottom if you need a reminder about any terminology or matrix classes. Singular Value Decomposition (SVD) Formula: Applies to: all matrices! Useful for: geometry Hot take: if you only know one matrix decomposition, make it SVD (forget Eigen). A 2x2 matrix has 4 degrees of freedom that describe a linear distortion on 2D vectors. The usual representation of can be unhelpful when reasoning geometrically. |
