How do I convert the following
164x11 char=
'03-Jan-2018'
'07-Jan-2018'
'07-Jan-2018'..
to 164x11 double=
'03-Jan-2018'
'07-Jan-2018'
'07-Jan-2018'
I want the elements to remain the same and just change the data type

Deprecated (and not recommended) would be
dn=datenum(yourdatechararray,'dd-mmm-yyyy');
which, of course, returns the datenum associated with the date; to get the representation use datestr. But, dn is a double.
The present (and recommended) way to handle dates is to use datetime instead --
dt=datetime(yourdatechararray,'InputFormat','dd-MMM-yyyy');
NB: the input format string representations are NOT the same between the two.
dt is its own class of datetime array, not a double. But, one can do comparisons of equality, greater/less than, etc., as well as plot and such have been extended to recognize the class as inputs.

I recommend turning the character data representing dates into a datetime array and using that datetime array along with your double data to create a timetable.
