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 ...

Y. Saad, Krylov Subspace Methods for Solving Large Unsymmetric Linear Systems, Mathematics of Computation, Vol. 37, No. 155 (Jul., 1981), pp. 105-126 ...

Combination of real and imaginary parts (CRI) works well for solving complex symmetric linear systems. This paper develops a generalization of CRI method to determine the solution of Sylvester matrix ...
