Hello, I am writing a function called check_possibilities.m where it takes as input the vector possibilities, and returns as output either I get stuck on the largest element of possibilities which is greater than or equal to 17, and less than or equal to 21.

So if "all" elements of the vector are greater than 21 return scalar 999, if "all" elements are 16 or lower return scalar -999 and otherwise return max of the vector?

Suppose that the vector of possibilities is [7 17] . Should it say "Oh, at least one value is in the range 17 to 21, so hold" ? Or should it say "Oh, at least one value is not in that range, so ask for another card" ?
If the current values were [11 21] you would certainly want to hold, but at [7 17] you might want to take another card in hopes of getting higher than 17 without going bust.

Ran in:
try this:
a=[9 13];
output_1=check_possibilities(a)
output_1 = -999
b=[23 34];
output_2=check_possibilities(b)
output_2 = 999
c=[9 20 19 22];
output_3=check_possibilities(c)
output_3 = 20
function y = check_possibilities(Arg1)
if min(Arg1) > 21
y=999;
end
if min(Arg1) < 21
y=-999;
end
if max(Arg1(Arg1>=17 & Arg1<=21)) >=17 & max(Arg1(Arg1>=17 & Arg1<=21))<=21
y=max(Arg1(Arg1>=17 & Arg1<=21));
end
end
