single_inter does not find intersection

OK.

BTW, you mean a bug in single_inter, may I assume? (Or in nsolve, as akmon asked?)

Anyway, I replaced the LN functions with ATAN functions (with different sets of fitted parameters), since I just needed more or less good approximations of measurement series. With ATAN the intersections could be found, and all related calculations could be traced perfectly. (And so at last I know now, why that %&*$-HF-Amp turnes to a HF.. attenuator over 50 MHz. :-))

Thanks and ciao,
