You could do something like this:

p=1:2:100000;
A=1;
T=2;
f=@(t)A/2 +2*A/pi*sum(sin(p*2*pi*t/T)./p);
t=0:.1:2;
for k=1:length(t)
    F(k)=f(t(k));
end
plot(t,F);

I assume A and T are scalar.

I think it basically works but why MATLAB told me error using in plot and vectors must be the same length.

Make sure you clear the variables before each use.
