The matrix stuff is also independent. If you split off the polynomial 
stuff you might also adapt the identifiers to qualified style.

Polynomial arithmetic is also contained in
    http://hackage.haskell.org/packages/archive/numeric-prelude/0.0.5/doc/html/MathObj-Polynomial.html
    http://darcs.haskell.org/htam/src/Polynomial.hs

vector-space seems to be a tough dependency, since it relies on type 
families. NumericPrelude's VectorSpace class is a multi-parameter type 
class.
