FFT is an alternative traceroute program for displaying the route packets take to an IP network host. Unlike Van Jacobson's traceroute, which is available on almost every platform today, FFT uses TCP in order to elicit ICMP TIME_EXCEEDEDs or TCP_RST. As a result, FFT often executes much faster...

EZFFT(T,U) plots the power spectrum of the signal U(T) , where T is a 'time' and U is a real signal (T can be considered as a space coordinate as well). If T is a scalar, then it is interpreted as the 'sampling time' of the signal U. If T is a vector, then it is interpreted as the 'time' itself....
