Dear experts, Hi

Unfortunately I faced difficulties in function plotting. I am apreciated If anybody could guide me how to plot when and & for instance.

Assuming it's not your homework (because you'd get into trouble for submitting our code as your own), try this:

x = linspace(1, 5, 500);	% Only 5 elements if we step by 1 so use more to get a smooth curve.
numberOfSums = 10;
Lx = 10 % A scalar.
n = 1 : numberOfSums  % 10 elements
omega = n .* pi / Lx  % 10 elements
for k = 1 : numberOfSums
    thisOmega = omega(k);
    fprintf('Building curve #%d of %d with omega = %.4f...\n', k, numberOfSums, thisOmega);
    thisCurve = sin(thisOmega .* x);
    if k == 1
        fx = thisCurve;
    else
        fprintf('    Summing in curve #%d of 10 to the master curve...\n', k);
        fx = fx + thisCurve;
    end
end
plot(x, fx, 'b-', 'LineWidth', 2);
grid on;

Thank you so much! Your guidances were helpful.

P.S. It's not my homework. You can rest assured!
