The original fftscope in simpower systems limits the usage to analyse the signals apart from simulink scopedata format.
This functions enables converts the signal structures into a power_fftscope format and performs fft analysis.
The function essentially a wrap around of power_fftscope which calculates the magnitude ,phase details of harmonic components of a given signal. Could be handy to analyse the electrical waveforms. (eg voltage, current)
Input method:
fft_list(data,time)
Where data & time are raw matrix in same length.
eg: fft_list(x,t,'f',50)
use help command for more information.
help fft_list

Note: Simpowersystems toolbox is necessary to run this function. Hence the first run might take few seconds to load up, but consequent runs are normal.
