**complex numbers How to find the imaginary roots of**

What I am doing right now is taking the derivative of the polynomial by using polyder then finding the roots of the N-1 th order polynomial by using the roots function in Matlab which returns N-1 solutions. Then I am picking the real root that really maximizes the polynomial. The problem is that I am updating my polynomial a lot and at each time step I am using the above procedure to find the... 15/06/2010Â Â· Hi Matlab users, I know fsolve can find the real roots from polynomial equations, but I don't know how to find complex roots, like x^2+1=0. Also I have a

For the roots: either use a polynomial for which you know the roots, or find the roots in advance, by using your own Newton solver. Here's the basin of attraction of the roots of \(z^5+1\): A plot of the basin of attraction with complex roots....
