Convert several columns char matrix into one column char matrix

I have a 200x12 matrix, with hours, minutes, seconds info. Each row has a time format like this: "13:35:43,050", but each column is composed of a single character of the time format ("1" in column 1; "3" in column 2; ":" in column 3, etc). I would like to end up with a 200x1 matrix, where all the column characters would appear in a single column, with no spaces. Can you help me, please? Thank you very much.

And your expected result for the above example would be?

I expect to obtain on every row the same time format "13:35:43,050" but with all the characters together in a single column and not separated into 12 columns. Thank you very much.

join?

>> tmp={'a' 'b' 'c' ; 'd' 'e' 'f'}
tmp = 2×3 cell    
'a'          'b'          'c'          
'd'          'e'          'f'          
>> join(tmp,'')
ans = 2×1 cell    
'abc'        
'def'
