routine to take the Fourier transform of a signal and plot both the time and frequency domain representations. Typical use: >> n = 100 number of data points >> dt = 0.01 spacing between samples >> t = 0:dt:(n-1)*dt time vector >> y = sin(2*pi*10*t) 10 Hz sin wave >> fft_plot(y,dt) plot of signal in time and frequency domain
