I am using this simple code inside a user defined Matlab function in SIMULINK

NumDays = daysact('20-March','21-March');

But it shows error that "Function 'daysact' not supported for code generation."

Correct. That function cannot be compiled.

The work-around is to use datetime and subtract.

dt1 = datetime('7-sep-2002','Locale','en_US')
dt1 = datetime
   07-Sep-2002
dt2 = datetime('25-dec-2002','Locale','en_US')
dt2 = datetime
   25-Dec-2002
NumDays = daysact(dt1, dt2) %what you cannot generate code for
NumDays = 109
NumDays2 = days(dt2-dt1)    %replacement function
NumDays2 = 109
