Calculating Time Intervals Between measurements

Hi, i have a set of values stored in vector Humidity. I have to first determine frequency of Humidity then use the frequency to calculate the time intervals between measurements and then store them in a nx2 vector : Time = [Hours Minutes] where hours are stored in the first column and minutes on the 2nd. The code below shows how i calculate my frequency but i do not know how to go about and find time intervals between measurements. Please help.

Humidity =38.4883

48.9108

38.1505

32.1763

49.5666

35.6956

48.6161

38.2022

45.4608

44.0763

45.9497

31.8542

44.8167

38.2594

39.1150

34.7962

37.1204

42.2333

37.2489

This is the code i used to calculate my frequency, am not sure whether it`s correct or not, please help.

for LenHumi = 1:1:length(Humidity)
    HumidityPeriod = (24/length(Humidity))*3600;
    HumidityFrequency = 1/HumidityPeriod;
end

Time is incorporated into frequency (cycles/unit of time). What are the units of your frequency? It looks like Hz, which means cycles/second.

[WILLBES BANDA]

the units of frequency are Hertz and the time vector should be something like this:

Time = 2 24

4 48

7 12

9 36

12 0

14 24

16 48

19 12

21 36

24 0

We would need to know something about the time course of data. Does your assignment contain any details?

[WILLBES BANDA]

it says that All measurements are taken over a 24-hour time period and that`s all it says regarding time
