Creating a function that identifies repeated items in a vector

I need help with creating this repeat function.
Write a function, repeat, that takes as input a vector of arbitrary length whose elements appear in random order. Determine whether the vector contains any repeated items. If it does, return true (1). Otherwise, return false(0). Test it in a program on the following vector: 11 22 33 44 55 66 77 99 11 102

testVector=[11 22 33 44 55 66 77 99 11 102];
result=(numel(testVector)~=numel(unique(testVector)))
if testVector has repeated item results would be true; otherwise it would be false.

You forgot to pass anything back! You need to pass "result" back out:
function result = repeat(v)
result = (numel(v) ~= numel(unique(v)));
end
Please mark the Answer as accepted if that works.
