There are many methods to do, the autocorrelation approach is easy and quite effective. You can calcute your signal's autocorrelation with
c=xcorr(y,y);
In your autocorrelation function it is easier to estimate the pitch.
You can have a look at this webpage http://iitg.vlab.co.in/?sub=59&brch=164&sim=1012&cnt=1
