read only time from date

I have dates in format 'yyyy-mm-dd HH-MM-SS.FF'. I want to calculate something starting only when time is 12-00-00. How can i do that (reading only the time from the date)? Thanks

[Y,M,D,H,MN,S] = datevec(___)

seems like it would do this, more information in

doc datevec

If you're using MATLAB R2014b or later, use datetime and timeofday:

>> t = datetime({'2017-01-19 11-35-12.34' '2017-01-19 12-25-23.45'},'Format','yyyy-MM-dd HH-mm-ss.SS')
t = 
  1×2 datetime array
   2017-01-19 11-35-12.34   2017-01-19 12-25-23.45
>> timeofday(t) > hours(12)
ans =
  1×2 logical array
   0   1
