Sort cell array by datetime
显示 更早的评论
I want to sort an array, that looks like the one below, by datetime.
70 26-Nov-2020 10:50:29
84 26-Nov-2020 10:00:00
79.5 26-Nov-2020 14:35:20
53 29-Nov-2020 12:31:00
Any idea how to do this?

Hello,
From my understanding, you want to sort the rows in the cell array according to the datetime values mentioned in the column.
Here is an example code (sorts in ascending order) using the data you mentioned:
% sample cell array
a = {70, '26-Nov-2020 10:50:29';
84, '26-Nov-2020 10:00:00';
79.5, '26-Nov-2020 14:35:20';
53, '29-Nov-2020 12:31:00'};
[~, idx] = sort(datenum(a(:,2), 'dd-mm-yyyy hh:MM:ss'), 1, 'ascend');
sortedData = a(idx,:);

Even better, since you're working with data where each column has a different type, consider using a timetable.
t = table2timetable(cell2table(a));
t = sortrows(t);
