Hi, I have the time stamps of a given signal xn, how can i compute the sampling frequency of this signal, it was not given?

If t is the time stamps, then he sampling frequency is
fs=1./diff(t)
you can check if the he sampling frequency is fixed or variable

If the sampling frequency is constant, all entries of the resulting array should be equal. If not, you could still calculate a 'mean sampling rate' with
fs = mean( 1./diff(t) )
To check if the sampling rate is constant you might do something like
is_const = all( diff( t, 2 ) == 0 )
