• How to calculate FFT in MATLAB?

  Y = fft(X); Compute the single-sided amplitude spectrum of the signal. f = Fs*(0:(L-1)/2)/L; P2 = abs(Y/L); P1 = P2(1:(L+1)/2); P1(2:end) = 2*P1(2:end); In the frequency domain, plot the single-sided spectrum.

• How to plot FFT using MATLAB?

  The fft function in MATLAB® uses a fast Fourier transform algorithm to compute the Fourier transform of data. Consider a sinusoidal signal x that is a function of time t with frequency components of 15 Hz and 20 Hz. Use a time vector sampled in increments of 1/50 seconds over a period of 10 seconds.
