N = 5;
A = 0;
w = 1; %where omega is equals to 2pi/tau and tau is equals to 2pi
a_0 = pi/4;
for i = 1:1:N
a_n = 2*(-1)^N-1 / pi*N^2;
A(i) = A + a_n;
end
I'm trying to make a fourier series code and this is part of it. I'm trying to save each value I get from that for loop and use it later for the calculation and plotting. My problem is that whenever I run this, I get an error message saying
In an assignment A(:) = B, the number of elements in A and B must be the same.
Error in test (line 9)
A(i) = A + a_n;
So as far as I understand, The first loop is going to be okay because A(1) will be a value of A+a_n, which is a sum of scalar, but from second loop, variable A becomes vector but a_n is still scalar so it's causing this error.
How do I solve this error and make it run?

I am not certain what you want.
Try this:
N = 5;
A = 0;
w = 1; %where omega is equals to 2pi/tau and tau is equals to 2pi
a_0 = pi/4;
for i = 1:1:N
a_n = 2*(-1)^N-1 / pi*N^2;
A(i+1) = A(i) + a_n;
end
