plot spectrum of a rectified sine wave using fourier coefficients in matlab

main.m
% Parameters
fs = 1000;  % Sampling frequency
f = 10;     % Frequency of the sine wave
t = 0:1/fs:1; % Time vector

% Generate rectified sine wave
x = abs(sin(2*pi*f*t));

% Calculate Fourier coefficients
N = length(x);
X = fft(x)/N;
X = X(1:N/2+1);
freq = 0:fs/N:fs/2;

% Plot the spectrum
stem(freq, abs(X));
xlabel('Frequency (Hz)');
ylabel('|X(f)|');
