So I want to make a wave that is on for 1ms and off for 1ms, lasting for 10ms. Is ther a function I can use to do this?

This is a slight variation on the method I showed you when you presented a similar problem yesterday in How to create a square wave pulse

t = linspace(0, 10E-3);                                 % Time Vector (0 - 10ms)
f = 5/max(t);                                           % Desired Frequency (Cycles/Timespan)
sqwv = sign(sin(2*pi*t*f));                             % Signal
figure
plot(t, sqwv, 'LineWidth',1.5)
grid
ylim(ylim*1.1)
xlabel('Time (s)')
ylabel('Amplitude')
