Expect that kron is used by repmat for the 2-D cases... repmat also special cases when numel(X) is 1, and handles N-D cases... Its a better habit to use repmat as its generic and just as fast..Is there an advantage to using repmat instead of kron as follows: kron(ones(m, n), X) vs. repmat(X, m, n)In 2.9.3 kron is built-in so it's a huge winner.
