Save the output of a for loop

Hey!

i am trying to generate 3 sine waves with different frequenceies using a for loop. I would like to save the output of this for loop in a matrix 500x3, but it is always overwrite the previous value. can anyone help?

See this example

f = [1 2 3]; % frequencies
t = linspace(0, 10, 500); % time values

S = zeros(numel(t), 3); % array for storing signal values
for i = 1:numel(t)
    s1 = sin(f(1)*t(i));
    s2 = sin(f(2)*t(i));
    s3 = sin(f(3)*t(i));
    S(i, :) = [s1 s2 s3];
end

plot(S)
