The test set should contain a polynomial with complex roots where the real part is positive, and a polynomial with a positive and a negative root.

I would have liked to use "tf" (transfer function) and "isstable", but these commands don't seem to be supported in Cody. :-(

This removes only polinomials if all the roots are positive. Should read 'all' instead of 'any' here.
