to accompany The Matrix Eigenvalue Problem: GR and Krylov Subspace Methods,

by David S. Watkins, professor of Mathematics at Washington State University .

Important Notice: These codes are for instructional and recreational use only. They were written with an eye to simplicity, so they lack certain safeguards that a foolproof code would possess. They have not been optimized for speed, nor are they guaranteed to be error free. If you need efficient, well-tested codes for your applications, use the built-in functions provided in MATLAB, or see LAPACK, ARPACK, HAPACK, etc.
