Get 10 seconds of a signal

Hi,

I have a signal, which has a fs= 15.5 Hz and having 76.266 samples of the signal, i would like to know how to extract segments of 10 seconds from the signal.

Thanks,

Regards,

A simple calculation to get the number of samples needed is:

number_of_samples = number_of_seconds)*(samples / second)

For 10 seconds, this is 10*fs, or a vector 155 samples in length:

idx = (0:154) + start_index;

where ‘start_index’ is between 1 and 76110.
