Time approximation in matlab

I collected 1500data during 24hours in my research. How can I know the number of data i recorded in 1hour?

Can you show some sample data?

If the sampling interval was constant:

SamplesPerHour = 1500/24

SamplesPerHour = 62.5000

Otherwise, you could use the retime funciton with the interval being 'hourly' and the aggregation method being 'count'.
