Is there an error in the code?

Day = [19980101];
[DayNumer,Dayname] = weekday(Day,DayForm);  

if DayNumber == 7
    disp('Take a rest today.')
end
 

Since 19980101 is saturday, DateNumber 7 is output.

7 has been printed, The 'Take a rest today.' shall be printed out.

However, it is not output.

Is there an error in the code?

Please help me. sir

There are some typos in your code, but it does what you want (is Saturday and the message is printed)

Day = 19980101;
[DayNumber,Dayname] = weekday(Day);
if DayNumber == 7
    disp('Take a rest today.')
end

>> Take a rest today.

Oh, that was easy.

Thank you very much for letting me know your knowledge. :)

You haven't converted the number to a date yet and you had a typo in your variable name. Also, 1998/01/01 was a Thursday.

Day = 19980101;
DayForm = 'long';
infmt = 'yyyyMMdd';

Day = sprintf('%6d',Day);
Day = datetime(Day,'InputFormat',infmt);
[DayNumber,Dayname] = weekday(Day,DayForm);

if DayNumber == 7
    disp('Take a rest today.')
else
    disp(Dayname)
end
