The Pseudoinverse - Numerical Linear Algebra

This discussion is all about the Moore-Penrose Pseudoinverse, or just Pseudoinverse for short. We explore the pesudoinverse numerically in python using numpy's linalg package. Check out the code plus some additional written notes: https://github.com/nkphysics/Computat... The Pseudoinverse leverages the Singular Value Decomposition (SVD) to work. If you need a refresher you can watch my discussion on the SVD here:    • Singular Value Decomposition (SVD) - Linea...   For overdetermined systems the pseudoinverse helps in producing a least squares solution. If you need a refresher on the method of least squares check that out here:    • The Method of Least Squares - Linear Algebra   My entire linear algebra playlist:    • Numerical Linear Algebra   The following links will take you to the papers by E. H. Moore and Roger Penrose for the Pseudoinverse: https://www.cambridge.org/core/journa... https://www.ams.org/journals/bull/192...
