The attachment has 1138 samples of datenum format.I want to find the sum of total hours in this order of index (2-1)+(4-3)+(6-5)+.....+(1138-1137). Any suggestions. The answer comes around 200 hours.

d = datetime(yourdatenumvector, 'ConvertFrom', 'datenum'); %convert to the more useful datetime
sum(hours(d(2:2:end) - d(1:2:end)))

In R2013a, it could possibly be calculated with:
sum(yourdatenumvector(2:2:end) - yourdatenumvector(1:2:end)) * 24
No guarantee that it works correctly. 2013a is ancient now.
