The Singular Value Decomposition (SVD) states that every matrix can be diagonalized using the proper bases for the domain and range spaces. MIT professor Gilbert Strang provides an existence proof for the SVD, broken down into an overview and details for clarity. The proof shows that a matrix A can be decomposed into UΣV^T, where […]
