Converting a timestamp into a value that can be plotted

Hi,

I have a timestamp data in the format of '11/04/2022 12:23:58 PM' '11/04/2022 12:24:04 PM' ... etc.

For me to able to convert this in a format where it can be used to plot a voltage as a function of time, it seems like I have to make some changes. I tried some of the methods that can be found online, but they did not seem to apply for the format I have for timestamp.

Any help would be appreiciated!

A duration array may woirk, although a datetime array would also work.

Perhaps something like one of these —

ts = ['11/04/2022 12:23:58 PM';'11/04/2022 12:24:04 PM']                                        % Text Time Stamps

ts = 2×22 char array
    '11/04/2022 12:23:58 PM'
    '11/04/2022 12:24:04 PM'

dt = datetime(ts, 'InputFormat','dd/MM/yyyy hh:mm:ss a', 'Format','yyyy/MM/dd HH:mm:ss')        % 'datetime' Array

dt = 2×1 datetime array
   2022/04/11 12:23:58
   2022/04/11 12:24:04

du = diff([dt(1); dt])                                                                          % 'duration' Array

du = 2×1 duration array
   00:00:00
   00:00:06
