Do NOT use the outdated, deprecated, imprecise DATESTR, DATEVEC, or DATENUM.
The DATESTR documentation states: "While datestr returns text representing dates and times, it is recommended that you use datetime values to represent points in time, and then convert them to text using the char, cellstr, or string functions."

Ugh, do NOT use DATESTR. This is easier without using the old, imprecise, deprecated functions:
aa = datetime('now','Format','ddMMM');
fn1 = sprintf('%s%s','DD-VTEC Vs UT,HYDE-IISC PRN PAIR DAY ',aa)
fn1 = 'DD-VTEC Vs UT,HYDE-IISC PRN PAIR DAY 27Dec'

Assuming you want the date formatted as ddmmm ( see additional format options ),
aa = datetime('now') % or aa = now() for double representation
aa = datetime
27-Dec-2021 17:45:06
s = datestr(aa,'ddmmm')
s = '27Dec'
fn1 = sprintf('%s%s','DD-VTEC Vs UT,HYDE-IISC PRN PAIR DAY ',s)
fn1 = 'DD-VTEC Vs UT,HYDE-IISC PRN PAIR DAY 27Dec'
