Renormalize intensity for real and complex roots together?
This app computes and plots all roots of functions of the form
for which all the coefficients \( \alpha_j \)'s are either \(+1\) or \(-1\) and the functions \( f_j(z) \) are arbitrary analytic functions on the complex plane. The functions \( f_j(z) \) can be selected using the pull-down menu above. The default choice of \( f_j(z) = z^j \) gives us \(n\)-th degree polynomials. The number of terms, \(n\), can also be changed.
