Impedance Determination through Differential Evolution FItting and eXtrapolation.

IDDEFIX is a tool for fitting resonators on impedance data using the Differential Evolution algorithm developed by Sébastian Joly. It computes the shunt impedance, Q-factor and resonant frequecny of the resonators present in the impedance data for both partially and fully decayed wakes. By incorporating the partially decayed resonator fitting, IDDEFIX enables the extrapolation of non-converged impedances.
