Hi,
I have two columns of cell values:

I want to merge these two columns to produce one third column in the format yyyy-mm-dd hh-mm-ss.
Thanks for any help!

c1 = {'2104-04-14'; '2014-04-14'} ;
c2 = {'13:17:08'; '13:16:45'} ;
datetime(strcat(c1,{' '},c2))

@John BG: Bob said "Thank you!" already, which sounds like the problem was solved. Then datetime works already. Maybe you did not understand, how datetime stores its data internally, but it does not matter what you set as display format. A calculation like "£301.- (YYYY-MM-DD)" is nonsense. If you need the value of a datetime object, you would e.g. use:
301 - day(B(1))
and for the output of day(B) it does not matter, if the date is displayed as YYYY-MM-DD or DD-MM-YYYY. This is the idea of datetime compared to the old serial date numbers or date vectors, where the display and the meaning of the dates and times were related.

Dear KSSV, your solution it really helped me in concatenating two cell arrays of character vectors into one cell array. Also, the cell arrays belonged to a data table. Thank you.
