Hi folks,
I have a cell of times (attached), which I need to read as numbers. Is there any way to do this?
Using num2str() doesn't work!
Thanks!

hello
you can do that (will simply combine minutes and seconds into only seconds time vector)
but as your original data has resolution of 1 second only and many duplicates, so will the resulting time vector.
you must improve the time resolution of your data
load('time.mat')
tmp = str2double(split(Time,':'));
time_seconds = tmp(:,1)*60 + tmp(:,2);

The data inside of Time variable are in time format like mm:ss. You can use datetime to extract them.
new_T = datetime(Time(1:end),'InputFormat','mm:ss','Format','mm:ss')
timeDuration = new_T-new_T(1);
timeDuration_inSeconds = seconds(timeDuration)
timeDuration_inMintues = minutes(timeDuration)
I hope, it works for you.
Note: num2str() will convert number to string. The output will not be number.
