Hi
i am getting valid_date (2018,4,1) output=1
and valid_date (2018,4,31) output=0
but i am getting error in
Assessment result: incorrect The last day of every month. Variable valid has an incorrect value
valid_date(2017,9,31) failed.........
Kindly point out the errors I have made!
function valid = valid_date(year, month, date)
if(nargin ~= 3)
valid = false;
elseif ((~isscalar(year)||(mod(year,1)~=0) || year<0))
valid = false;
elseif ((~isscalar(month))||(mod(month,1)~=0) || (month<=0) || (month>12))
valid = false;
elseif ((~isscalar(date))||(mod(date,1)~=0) || (date<=0))
valid = false;
elseif(any(month==[1:2:7,8:2:12])&& date>31)
valid = false;
elseif (any(month==[4,6,9,11]) && date>30)
valid = false;
elseif month==2 && date>(28+(mod(year,400)==0 || (mod(year,100)~=0 && mod(year,4)==0)))
valid=false;
else
valid = true;
end

I verified that your program correctly returns that valid_date(2017,9,31) is false.
It looks like you are using some kind of test script to see if your program is working properly. Maybe there is a problem with this test script, because your program seems to work OK.
