Write a function called valid_date that takes three positive integer scalar inputs year, month, day. If these three represent a valid date, return a logical true, otherwise false. The name of the output argument is valid.
unction valid = valid_date(year,month,day) if year < 1 || ~isscalar(year) || year ~= fix(year) valid1 = false;...
