Hi guys,
How could I convert time stamps to a num or double, this is the format I have:
'09:35:00.000' '09:36:00.000' '09:37:00.000' '09:38:00.000' '09:39:00.000' '09:40:00.000' '09:41:00.000' '09:42:00.000'
I tried str2num str2double with various arguments... but got no where , I am assuming that the format of the time stamps is not read by those functions maybe, is there any function that am missing? Your help is appreciated.

It would be helpful if you define the wanted output. What do you want for '09:35:00.000' ?

Hi Jan,
You are right I should have been more detailed by expressing a format like 'hhmmss' for example ..

A = {'09:35:00.000' '09:36:00.000' '09:37:00.000' '09:38:00.000' '09:39:00.000' '09:40:00.000' '09:41:00.000' '09:42:00.000'};
out = datevec(A)
out = out(:,4:end)

A = {'09:35:00.000' '09:36:00.000' '09:37:00.000' '09:38:00.000' '09:39:00.000' '09:40:00.000' '09:41:00.000' '09:42:00.000'};
B = sprintf('%s:', A{:});
C = reshape(sscanf(B, '%g:'), 3, []);
Then you have:
C = [ 9 9 9 9 9 9 9 9
35 36 37 38 39 40 41 42
0 0 0 0 0 0 0 0];
If you want to convert it to seconds:
D = [3600, 60, 1] * C;
