I saw an article, "the top 10 algorithms for the 21st century".  
One of these was Krylov subspaces.

Can anyone clue me in what this is, and what for? Not
looking for a math seminar, more like apps. And why
is the algorithm, whatever it does, so important?

If I wanted to research this further, would it be
a linear algebra book, or numerical analysis, or what?
