Hello, I want to make a Pulse train(for a simulation of the switching a dc-dc boost elevator). Here is my code.
dur=input('Please set the time the wave will last: ');
per=input('Please set the Period: ');
duty=input('Please set the Duty Cycle: ');
t=0:dur/1000:dur-dur/1000;
ton=ones(1,floor(1000/(length(dur)/(per*(duty/100)))));
toff=zeros(1,ceil(1000/(length(dur)/(per*((100-duty)/100)))));
normal=[ton,toff];
y=repmat(normal,1,(length(dur)/per));
plot(t,y);
But I am having a lot of problems for floating numbers of periods, duty cycles and so on...
Any idea of how to improve or make it really efficient?

why not try something like this:
t=0:per/1000:per-per/1000; %define period
normal = zeros(1,numel(t));
normal(t<per*duty/100))=1;
then just remap this to either equal the total duration or just above and then cut to length.
