Code exmaple:
Fs = 1 / (time(2) - time(1)); %sampling frequency
N = length(amplitude);
fs = Fs * (0:(N/2))/N;
set = struct("SamplingFrequency",fs,"FFTLength",N,"Mode","onesided");
[s,f,set] = autofft(amplitude,fs, set);
%amplitude_spectrum_dbv = 20 * log10(abs(s(1:N/2+1)));
disp(set)
figure;
plot(fs, s);
xlabel('Frequency (Hz)');
ylabel('Amplitude (Amplitude)');
title('Frequency Spectrum using autofft');
grid on;

The above is the code that i'm working on, its for creating frequency plot from amplitude , time data. I've installed the Auto_FFT from Add-ons in Matlab. I already shared the error i'm facing.
