How to get sample rate from a matrix of time?

I have an EMG signal and when i load the .mat file it gives me a matrix with the data and another with the time . How can i get the sample rate from the matrix of time?

Assuming the time is regularly sampled, there are two ways:

Ts = t(2) - t(1);

or:

Ts = mean(diff(t));

where ‘t’ is the time vector.

The sampling and Nyquist frequencies are:

Fs = 1/Ts;
Fn = Fs/2;
