compute the frequencies and the amplitudes of the first seven fourier coefficients of a rectified half-wave 50hz sine in matlab

main.m
% Define the parameters
f = 50; % Frequency of the sine wave
fs = 1000; % Sampling frequency
t = 0:1/fs:1; % Time vector

% Create the rectified half-wave sine wave
x = abs(sin(2*pi*f*t)); 

% Perform Fourier transform
X = fft(x);

% Calculate the frequencies
frequencies = (0:length(X)-1)*fs/length(X);

% Compute the amplitudes of the first seven Fourier coefficients
amplitudes = abs(X(1:8));

% Display the frequencies and amplitudes
disp('Frequencies:');
disp(frequencies(1:8));
disp('Amplitudes:');
disp(amplitudes);
