The DSP package on Hackage seems to contain complex polynomial functions.
It seems these functions are completely independent of the other DSP functions, 
so this
package could be split of?

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

Also, polynomials form a vector space, so could be made an instance of 
VectorSpace class?

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.
