Given twovectors A & B, I'm trying to figure out how to get a numel(A)-by-numel(B) logical array C wherein C(i) is the result of ismember(B',A(i)) without using a for loop. I've tried feeding repmat'ed and tranposed versions of A & B into ismember, but to no avail.
How can I achieve the same result as
A = randi(11, [500 1]);
B = randi(10, [250 1]);
C = false(500,250)
for i = 1:numel(A)
C(i) = ismember(B',A(i));
end
without the for loop? If the answer is arrayfun, is that really any faster than a for loop?
