MATLAB: How to find out missing dates from the given data

Question

I have the data on daily basis year wise, each day 2 observations and if i need the data from June to Sept, how i can separate in that format, if once i got the data in this how can i find out missing values in that.

Answer 1

You convert your dates into date numbers using datenum. Create your required dates into date numbers and then use ismemebr or intersect

Eg:

d0 = '01-June-2017' ;
d1 = '30-Sep-2017' ;
d = datenum(d0):datenum(d1) ;
days = datestr(d) ;
