MATLAB: Comparing vectors of different size

Question

How do I compare two vectors of different size? I want to compare them using the "greater than or equal to operator" or "less than operator". Here's what I'm trying to vectorize:

A = [1 2 3 4 5]; B = [1 2 3]; for i = 1:length(B) C = find(A >= B(i)); end % C = [3 4 5]

Answer 1

C = A(all(bsxfun(@ge,A,B.')));
