Would we want to look at implementing these algorithms interms of
lazy matrices and promises?

Let me take a broad stab at a couple of different levels.  At the 
highest level, the canonical set of problem classes for numerical 
linear algebra consist of:

o) Solving linear systems of equations
o) Solving least-squares problems (e.g., over and under determined 
systems)
o) SVD
o) Eigensystems
