logging time and data and store it in a matrix

Hello,

I am using a National Insturments device with analog inputs.

I want to meassure the voltage of a analog port and store the date and time (with every meassurement) in a matrix next to the data of the analog port.

example:

date time data

24/4/2021 12:53:20 1.13

24/4/2021 12:53:21 1.14

24/4/2021 12:53:22 1.15

What is the best way to achieve this?

It is possible to use detectImportOptions and set the variables, however I find the following approach easier:

T1 = readtable('Niet hier Example File - 2021 04 24.txt');
date_time = T1.date+T1.time;
date_time.Format = 'dd/MM/yyyy HH:mm:ss';
data = T1.data;
T2 = table(date_time, data);

producing:

T2 =

  3×2 table

         date_time         data
    ___________________    ____

    24/04/2021 12:53:20    1.13
    24/04/2021 12:53:21    1.14
    24/04/2021 12:53:22    1.15
