I am trying to get durations of a reoccurring event in a timetable by taking the datestring of a file and removing a duration from the timetable. When I try to convert the datestrings in a structure, all but the last row is output as NaT. I've tried setting the input format as well. For some reason I got it to work once but when I added it to my function this problem started happening.
I've pasted the for loop below and in this editor it seems to be working but I'm confused as to why it doesn't work in my function.
load sweep_data.mat
for n = 1:length(sweep_struct)
sweep_datetime(n,1) = datetime(sweep_struct(n).date);
end

Ran in:
Avoiding the loop is easy:
S = load('sweep_data.mat');
D = datetime({S.sweep_struct.date}).'
D = 323×1 datetime array
