Pulse train with duty cycle variable.

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.
