MATLAB: Export data based on latitude and longitude from 3 dimension array

Question

Dear all Matlab professionals

I have an array named precipitation with 3 dimension (longitude*latitude *time) which it's valued represents precipitation for all around the world at 10*10 degree for 1980 to 2016.

I have 2 question:

1. how to convert third dimansion unit (time) from days since 1800 to common date unit like 2010-1-1?
2. how to export data form it for a selected range of latitude and longitude and selected time like 1982-2015?

I attached some information below:

whos lon lat time precipitation
  Name               Size                   Bytes  Class     Attributes
  lat               1x18                     144  double              
  lon               1x36                     288  double              
  precipitation        36x18x1512            7838208  double              
  time               1512x1                    12096  double
              

Thank you all in advance and I'm looking forward to your answers.

Best regards

Hi Bekzad,

here is the answer:

load time
TT =datetime(t, 'convertfrom', 'excel');

Now TT are dates.

Good luck.
