Hi everyone,

I have a vector (time1) that conain 'year', 'month' and 'day' in this format '19850101'. Is there a way to modify this format separating 'year', 'month and 'day'? Thanks.

Hi,

you convert to string your time vector (num2str function) and then convert it to date (datetime function), specifying input format as follow:

time1_str = num2str(time1);
time1_date = datetime(time1_str,'InputFormat','yyyyMMdd','Format','dd-MM-yyyy');

Note that you can decide output format (in my example is dd-MM-yyyy).

Hope this helps.
