How to add a matrix vertically and nest an if loop

Hi, i have a vector OxygenT = [0 5] and i want to add [0 5] to the next row so that i get 0 5

0 10

. .

. .

and i want it to continue until it equals the length of vector Oxygen below

Oxygen = 21.9599

22.6469

22.4288

19.0584

21.8578

24.4726

24.0144

19.7079

22.6187

24.2526

19.1982

23.0555

21.2375

19.7511

22.3351

20.9603

21.7795

19.3307

23.0599

Since i am dealing with time, how can i nest my loop such that when minutes(2nd column) reach 60 then 1 hour is added to column 1

Below is my code but when i run the code i only get 2 rows and it doesn`t add up until length of Oxygen. Please help

OxygenT = [0 5]
if length(OxygenT) <= length(Oxygen)
secondtime_interval = [OxygenT + OxygenT]
Oxygentime=[OxygenTime;secondtime_interval]
end

Using a loop for this would be pointless and unnecessary complicated

Oxygenminute = (1:numel(Oxygen))' * 5;
Oxygenhour = floor(Oxygenminute/60);
Oxygenminute = mod(Oxygenminute, 60);
Oxygentime = [Oxygenhour, Oxygenminute]

An even better solution is to use a duration type instead of splitting the time over two columns:

Oxygentime = minutes(5) * (1:numel(Oxygen))';
Oxygentime.Format = 'hh:mm'

It works perfectly, thank you so so much honourable
