How to plot continuous on off signal using mod-command

Hi

I need to figure out how to generate a simple continuous on-off signal, by using mod-command.

Got an m-function already

function y=jj(x,a,b)

y=a+mod(x-a,b-a);

The solution must be very simple, but I can't get my head to figure it out.

The sample graf that I have is attached.

Hope you understand my dilemma.

Thanks

The question is not clear. You cannot "create a continuos signal". So please explain, what you want to get as output. What is x, a and b in your code?

Sorry for the insufficient question.

The assignment that I have is to make a function that generates that given figure.

And the subfunction that I should use is that

Function y=jj(x,a,b)

y=a+mod(x-a,b-a);

Thats what I have at the moment.

The signal is continuous on-off and it goes on and on, bothways from the zero.

Hope you understanded my task.
