How to find the period time of a signal if given only one period of the signal ?

Hi,

I am a begginer in matlab and i suppose it's a relatively simple question, I have a question which I have to find the period time but it's given to me only the signal itself and more precisely one period of the signal so how can I find the length of this signal ? Is there maybe any function ? And also just to know for the next time how do we find the period time when it's not just given one period ?

I looked on google and this forum but the answers weren't very precises.

Thanks

If the entire length of the signal is known to be exactly one period, then the period is the length of the signal

period = length(signal);

If you have separate time or x vector and a separate signal or y vector, then the period is the distance between the first and last element.

period = x(end) - x(1); % or t(end) - t(1)
