Hi Devidutta,
The 'datestr' function is not recommended to be used since R2022b as mentioned here: https://www.mathworks.com/help/matlab/ref/datetime.datestr.html
Alternatively you can use this following approach to acheive your desired date & time format:
% Original date string, separated by semicolon
dateStr = '10/12/2024; 10:58:49';
% Convert to datetime
dt = datetime(dateStr, 'InputFormat', 'dd/MM/yyyy; HH:mm:ss');
% Format the date using the datetime display format
dt.Format = 'dd-MMM-yyyy HH:mm:ss';
% Display the result
disp(char(dt));
For more information on 'datetime' function, please refer to https://www.mathworks.com/help/matlab/ref/datetime.html
Hope this helps.
