I'm trying to get this function to plot but the actual figure won't come up. The script is running but the figure itself wont come up, I tried to put figure() but still nothing

N=5;
NTime=1000;
dt = 2/NTime;
t=--dt;
for k=1:NTime
    t=t+dt;
    time(k)=t;
    f(k)=0;
    for i=1:N
        f(k)=f(k)+((-2/i*pi)*((-1)^i)/sqrt((1-(2*i*pi/2))^2+(2*0.05*2*i*pi/2)^2))*sin(2*i*pi*t);
    end
end
plot(time,f,'r-')
hold on
axis([0 2 -1.5 1.5])

在 MATLAB Online 中打开

Parker - have you already run the code so that the figure appears, then when you go to run the code again (without closing the figure), it doesn't re-appear? Because the figure might be behind the MATLAB app. Try closing all figures with

close all;

before your code.
