Specific timestamp to date format using datetime

I have data with a certain timestamp, being yyyymmddHHMM and I want to convert this to time format in matlab:

For example:

Given a timestamp of 201502171000 I want to get 2015-02-17 10:00.

PS: I have to manage a lot of data for a given time unit and my aim is to identify my measurements for that certain time unit. And thats why I thought that time format could be helpful.

This works:

T =  201502171000;
str = num2str(T, '%11d');
dn = datenum(str, 'yyyymmddHHMM');
ds = datestr(dn, 'yyyy-mm-dd HH:MM')                                            % ‘Legacy’ Functions
dt = datetime(str, 'InputFormat','yyyyMMddHHmm', 'Format','yyyy-MM-dd HH:mm')   % ‘datetime’ Function

I do not know if you are starting with an integer or string, so I included the conversion from integer to string, necessary for the datetime function.

Thanks! Now I have another problem, I have the time array and a data array.

My purpose is to make a loop as:

For each hour ( the data time is hourly), so for 2015-02-17 10:00, 2015-02-17 11:00 and so on

Use the values of the array UP ( in the picture) to do certain mathematical operations

Thanks for all in advance!

My pleasure.

I am not certain what you want to do.

If you want to put your datetime object and your data together, I would use the table function, since it is designed for that. Another option is a cell array.

Assuming you have strings, not numbers, you've kind of answered the question yourself, except for m vs. M:

>> datetime('201502171000','InputFormat','yyyyMMddHHmm')
ans = 
  datetime
   17-Feb-2015 10:00:00
