I have a matrix called time_stamps which contain several time stamps for twitter data (when the tweet was posted). time_stamps is a 1645x5 char array right now. It contains 5 columns (12:44 is a time stamp with 5 characters). With this, I am trying to find the minimum time stamp and the maximum one. Which time is the least and which time is the most? I'm having trouble writing the code to do it though. Any help you can give would be much appreciated.
tunedData = readtable('parsed_tweets_small.csv');
time_stamps = table2array(tunedData(:,4));
time_stamps = cell2mat(time_stamps);
%now i need to find the minimum and maximum of these time stamps
