I want to count number of hours for condition if (PPD<6 and fOcc=1) then count the number of hours and put them in tables ...how can i make these in matlab?

sherif - you may need to provide more details. What is the data that you are looping over? What data do you want to put into tables?

[Peter Perkins]

Generally speaking, you would have your data in a table, create logical vectors to find PPD<6 and fOcc=1, and those together, and look for runs of trues. With no more information to go on, hard to say more.
