Manipulating tensor products

If I have computed an integral of something of the form kron(A,B) where A and B are sparse matrices. How do I get other tensor products such as kron(A',B), kron(A, B'), etc? Since they all involve the same elements it should be a simple manipulation of the indices. Is there an existing routine to do this?

Transposition is distributive over the Kronecker product, so
kron(A',B') = kron(A,B)'
kron(A',B) = kron(A,B')'
but there doesn't seem to be a simple way of getting kron(A',B) or kron(A,B') from kron(A,B).
