flag = 'KLAX 312353Z 27009KT 10SM FEW200 18/10 A3007 RMK AO2 SLP182 T01780100 10217 20178 55007'

I need to find extract 312352Z from the string using I tried regexp(flag, '\d{4}\Z', 'match');

I am sure the syntax is not correct. What is the correct syntax? Thanks in advance.

You need to tell regexp that you’re looking for the beginning and ending of a particular word:

wx_time = regexp(flag, '\<\d*Z\>', 'match')
wx_time =
    cell
      '312353Z'
