Finite-element solution of Sturm-Liouville problem

[leon_avery]

Can someone point me to a simple introduction to the use of finite-element methods to find eigenvalues and eigenfunctions for a Sturm-Liouville problem? In my searching I've seen various suggestions that this is now the dominant method, but I've had no luck in finding an actual explanation, with examples.

Thanks for any help!

There is an article focusing on eigenvalue problems in the Volume 2 of the Handbook of Numerical Analysis written by I. Babuška and J. Osborn (I don't know if this qualifies as a simple introduction though...)

Thanks! I'll check whether our library has that.
