How to calculate the deviation or difference between two arrays of datetime?

Hello everybody,

I try to compare two timelines of the same event, to analyse the synchronicity.

dt= between( H , I,'time' );

I really have no idea how to do it, that I arcieve a new filfe consiting only the numeral deviation of each "row" (10 in this case)

I hope I desrpibed my problem good enough, files are attached. format is Time_Relative_hmsf_-

Thanks for help :)

Here is something to start you off.

H = readtable('https://www.mathworks.com/matlabcentral/answers/uploaded_files/1501395/H4L.txt');
L = readtable('https://www.mathworks.com/matlabcentral/answers/uploaded_files/1501400/I4R.txt');
diff = L.Var1 - H.Var1

diff = 10×1 duration array
    00:00:00.000
    00:00:00.000
    00:00:00.000
    00:00:00.000
   -00:00:00.040
    00:00:00.000
   -00:00:00.040
   -00:00:00.040
    00:00:00.000
    00:00:00.000

Didn't recognize that it is that easy, thank you!

Since you are only reading vector of duration values from the files and you dont really need tables, this can be simplified further by using readmatrix.

H = readmatrix('https://www.mathworks.com/matlabcentral/answers/uploaded_files/1501395/H4L.txt',OutputType='duration')

H = 10×1 duration array
   00:03:21.720
   00:03:22.560
   00:03:23.440
   00:03:24.280
   00:03:25.160
   00:03:26.040
   00:03:26.920
   00:03:27.800
   00:03:28.640
   00:03:29.480

L = readmatrix('https://www.mathworks.com/matlabcentral/answers/uploaded_files/1501400/I4R.txt',OutputType='duration')

L = 10×1 duration array
   00:03:21.720
   00:03:22.560
   00:03:23.440
   00:03:24.280
   00:03:25.120
   00:03:26.040
   00:03:26.880
   00:03:27.760
   00:03:28.640
   00:03:29.480

L-H

ans = 10×1 duration array
    00:00:00.000
    00:00:00.000
    00:00:00.000
    00:00:00.000
   -00:00:00.040
    00:00:00.000
   -00:00:00.040
   -00:00:00.040
    00:00:00.000
    00:00:00.000
