I have a large set of dates and times in a string array and I need to search for a smaller string of dates and times within the large set. I have tried using strfind and strcmp but can't seem to manage it.
It's also possible that the dates and times won't match up perfectly (they may differ by some number of seconds, I will figure out a suitable time when necessary), so is it then also possible to use a conditional statement on a string so that I can do the search?

"I have a large set of dates and times in a string array ..."
This is what I found in the uploaded files (opened using R2015b):
>> FileTimes
FileTimes =
""
>> SDT
SDT =
""
>>

That's strange, here's the whole workspace (if that helps). Files in question are 'SDT' (large set of dates) and 'FileTimes' (small set).
