Solving Linear Systems (SymPy) Most linear algebra courses start by considering how to solve a system of linear equations.

We can combine these three matrices into a single linear system, where the first matrix multiplied by the unknown values of the second matrix equals the third matrix — at which point we can use linear ...

Algebraic multigrid (AMG) methods have emerged as a crucial tool for efficiently solving large, sparse linear systems, particularly those arising in complex scientific and engineering simulations.

Mathematics of Computation, Vol. 23, No. 108 (Oct., 1969), pp. 787-812 (26 pages) The mathematical and numerical least squares solution of a general linear system of equations is discussed.

We also completely characterize the set of solutions for n = 2 using commutative algebraic techniques. The journal publishes original papers in all areas of pure and applied mathematics. Consists of ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
