I have a few hours worth of wind speed data and need to locate ten minute intervals which all have similar mean wind speed, turbulence intensity and peak value.
thanks

If you have a timeseries ts you could do the following (assuming your timeseries is in seconds)
idx=ismember(ts.Time,[600:600:length(ts.Time)]); % 600 seconds being 10 minutes
ts.Data(idx)
If you don't have exatly 10minute intervals, for example the nearest value to 10 minutes is 10min 01 secs, you may need to opt for ismembertol instead of ismember.
