I am trying to plot N versus error and nothing shows up in the plot.
I am not getting any errors but its not plotting anything.
Any advice is appreciated, code is below.
w = pi/2;
t = 0:0.01:4;
x = t.*(0<t&t<2)+(4-t).*(2<=t&t<=4);
for N = 1:10
Ao = 1;
for q = 1:N
xhat = xhat+(-2./((q.^(2).*pi.^(2)+N))*exp(1i*q*w*t))
xhat = xhat+(-2./((-q).^(2).*pi.^(2)+N)*exp(1i*(-q)*w*t))
error(N) = mean((x-xhat).^2);
