I'm trying to define a function which is a series of rectangular pulses, where the length of a pulse increases by a constant with each repeat. The distance between the pulses should remain the same.
How would I do this in MATLAB?

How about using modulate function (Signal Processing Toolbox)?
The following is an example:
fs = 100;
fc = 5;
data = 0:0.2:1;
y = modulate(data,fc,fs,'pwm');
% Plot the waveform
figure
plot(y)
ax = gca;
ax.XTick = 0:20:120;
ax.YLim = [0 1.2];
grid on
