For a vector v with N components, return the roots of the polynomial
v(1) * z^(N-1) + ... + v(N-1) * z + v(N)As an example, the following code finds the roots of the quadratic polynomial
p(x) = x^2 - 5.c = [1, 0, -5]; roots(c) 2.2361 -2.2361Note that the true result is +/- sqrt(5) which is roughly +/- 2.2361.
