I have a matrix Q (nx2*n*m) that Rank(Q)<n must be satisfied. That means that there's a row nullity, but RowReduce can't work it out.
Q is of the form Q=[B|AB|---|A^(2*n-1).B],
where A(3x3),B(3x2) Matrices.
It is amazing though that If I RowReduce A,B before the construction-calculation of Q I end up to Rank(Q)<2, but instead of elements of A,B I get 1and0's. Any proposals to get a Q with Rank(Q)<n&the elements I need?

Thanks in advance,
Leonidas
