Detailed Description

Find all the roots of a univariate polynomial with complex coefficients. Class to find all the roots of a univariate polynomial f with complex coefficients. Currently works by computing the eigenvalues of the companion matrix of f.

The input vector a of coefficients are given to the constructor. The polynomial is f = t^N + a[0] t^{N-1} + ... + a[N-1] The roots can then be found in the 'solns' member.
