Convert duration from MM:SS to M:SS.

Hello everyone, I have a duration vector like this:

     00:00
     00:01
     00:01
     00:02
     00:02
     00:03
     00:03
     00:03
     00:05

It only goes from 0 to 4 minutes so, in the plots I don't want to show something like: 01:05, but rather 1:05. That is, I want to get rid of the first digit and convert from mm:ss to m:ss. Is this possible?

Thank you for your time, Gianluca

Hello!

In order to achieve the desired time-format (or date format) you have to take a closer look at the function "datetime".

I tried the following code by myself and it should give the result you wish to achieve:

%Code

% Set up the vector (just for me to test) containing the time 'mm:ss'

a= ["01:00";
     "01:01";
     "01:01";
     "01:02";
     "01:02";
     "01:03";
     "01:03";
     "01:03";
     "01:05"];

   % get the size of a 
   [rowsA colsA] = size(a);

   % loop through the array in order to change the time-format

   for i=1: rowsA
     a(i)= datetime(a(i), 'InputFormat', 'mm:ss', 'Format', 'm:ss'); 

   end

I hope this answer was helpful.

Kind regards, Florian

I forgot to mention that the class of the variable is "duration", so that code does not really work in this case. But I think I have found the solution: |

a.Format = 'm'

I still don't know whether I like it because in this case I get:

     0 min
     0.016667 min
     0.016667 min
     0.033333 min
     0.033333 min
         0.05 min

I think I'd rather have just the number without the "min". I don't know whether that is going to create problems with the plots. But we'll see.

Anyways, thank you very much for your answer.
