But the above code doen't seem to contain functions to find (or approximate) all complex roots, which is the function I need (maybe with special cases for linear, quadratic, cubic, since these can be done analytically). The DSP package does, albeit only Laguerre's method, which might be good enough, although my old C# code that I wanted to port used Weierstrass method <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. NumericPrelude is very impressive, but it scares me a little, since it is so big :-)
