How to verify input only contains certain numbers?

Lets say that users are required to enter the numbers: 35, 36, 37 in some order (b={'35', '36', '37'}). How would I go about verifying that these numbers were entered and not some other numbers and that each number was only entered once? So if the user entered 30,36,37 or 36,36,37 the program would error. The only acceptable input would be one where 35, 36, and 37 occur only once, in any order. Any ideas?

An idea

>> b={'37', '36', '35'};
>> all( strcmp( unique( b ), {'35','36','37'} ) )
ans =
     1

However, you have to check that length(unique(b))==3 before applying strcmp

Perfect, thanks!

Now I'm having some issues. I have two cell arrays, 'runs' and 'z7prtests'.

runs = {'27' '28' '108' '109'};
z7prtests = {'27' '28' '108' '109'};
all( strcmp( unique( runs ), z7prtests ) )
ans =
     0

This doesn't seem to be working, any ideas?
