A couple of quick suggestions that may be a trifle too radical.


The first is FFTs and related thingumajigs. My experience is that
they come in shortly after eigenvalues as the most heavily used
numerically intensive matrix methods.


The second is graph-theoretic algorithms. Let's view a matrix as
a distance graph - there are LOTS of important algorithms that
munge over those things.


Sven will not be surprised that I have posted these suggestions;
he has had me go on about them often enough :-)
