I downloaded precipitation data from SIM2RAIN. It is 3 dimensional and temporal resolution is 1 day. For example for year 2005, my file size is 365(days)*1440(long)*720(lat). I want to show precipitation data for each day in matrix (1440,720). So, It means ı will have 365 files. My file name is CCI_SM2RAIN_2005_BC.nc. I can do it by using Arcmap but it is very time consuming. How can I do this in matlab ? Thanks for help.

You can read your nc file like shown below....Change the variables in the below to your variables naming converntion in your file.
ncfile='CCI_SM2RAIN_2005_BC.nc'
lon = ncread(ncfile,'Longitude') ; nx = length(lon) ;
lat = ncread(ncfile,'Latitude') ; ny = length(lat) ;
time = ncread(ncfile,'Time') ;
for i = 1:length(time)
z = ncread(ncfile,'Rainfall',[i 1 1 ],[1, nx ny]) ;
z = squeeze(z) ;
pcolor(lon,lat,z') ;
title(sprintf("Time step = %d",i)) ;
shading interp
drawnow
end

Also you can read the entire data into MATLAB workspace using:
z = ncread(ncfile.'Rainfall') ;
for i = 1:length(time)
R = squeeze(z(i,:,:)) ;
pcolor(lon,lat,R')
shading interp
drawnow
end
I have edited the original answer again.....now it will work..check it.
