>> find(date<='01-Apr-2013 00:00:00' & date>'01-May-2013 00:00:00')
ans =
1×0 empty double row vector
Why am I getting this as an answer and not a vector of the dates I am trying to pull from the data?

You are looking for a date that is both before 01-Apr-2013 and after 01-May-2013. Since May is after April, no such date exists, obviously find is going to return empty.
