When producing a spectrum with fft.m there is no build-in m-file to find the corresponding y-axis. Example; if you want to plot the real Fourier coefficients of a signal (y) with corresponding time (t), write 'plot(freqspace(t),real(fft(y)))'. Created while finding derivatives in the Fourier sense, i.e. dy/dt=ifft(2i*pi*freqspace(t).*fft(y),'symmetric'); Uses ifftshift.m and linspace.m.
