Hi @Campbell
I understand that you are encountering an error while plotting Fourier Sine Series. I investigated the attached code and found that error is realted to the absence of 'nl' input argument while calling the 'fourierSineComponents' function. One of the workarounds to resolve the error is adding a call to the function 'fourierSineComponents' above the function definition in the MATLAB script. For example, you can add the following line at the top of your script.
fourierSineComponents(1) % customize the value as per needs
function fourierSineComponents(nl)
Furthermore, an alternative workaround involves invoking the script while providing the 'nl' argument. For instance, if your script is named 'script.m', then you can execute the code from the command line as follows.
>> script(1) % customize the value as per needs
Selecting any of the above options would be sufficient to fix the issue. Moreover, while reviewing the code, I observed warnings related to the assignment of vectors 'A' and 'F'. These warnings are raised to draw attention to the fact that the sizes of these vectors are being modified in each iteration. This could potentially decrease performance and speed of the code. Hence, to enhance performance, particularly in terms of speed, I highly advise preallocating these vectors. Here is a code snippet for your reference that does the same.
A = zeros(1,300); % prealolocating A and F for enhanced performance
F = zeros(1,300);
for n = 1:300
A(n) = -3*pi + pi/50*(n);
end
for n = 1:300
F(n)= pi/2;
end

I hope this helps.
