how to extract indices?

Hi,

I am trying to loop in time to extract it within the range of 23 to 1am and 11am to 13 using the following find function:

my problem is to do that for the days from 20 to 31 of March.

how can I loop over it? and extract the indices?

Note, the mtime is a 2D matrix which I need the first row for all column (1,:)

ntime=find(mtime>=datenum(2019,3,20,11,0,0) & mtime<=datenum(2019,3,20,13,0,0)...
           & mtime>=datenum(2019,3,20,1,0,0) & mtime<=datenum(2019,3,20,23,59,0));
