We introduce the (Moore-Penrose) pseudoinverse of a matrix, which exists for all matrices (and equals the usual inverse if it exists). We show how to compute the pseudoinverse via the singular value decomposition. • Textbook: http://www.njohnston.ca/publications/... • Blank course notes (lectures 38-41): http://www.njohnston.ca/ala_week10.pdf • Annotated course notes (lectures 38-41): http://www.njohnston.ca/ala_week10_an... • Please leave a comment below if you have any questions, comments, or corrections. • Timestamps: • 00:00 - Introduction • 00:47 - Invertibility and linear systems • 03:52 - Pseudoinverse definition • 08:25 - 3x4 example
