Unit 6 · Symmetric Matrices, Positive Definiteness, and the SVD

Chapter 6.3

Similar Matrices and the Singular Value Decomposition

Similarity sorts matrices into families with shared eigenvalues — and the SVD ends the course's factorization story: any matrix at all becomes UΣVᵀ, rotation-stretch-rotation.
