Suppose each element of matrix A is the linear presentation of n independent variables. And matrix B is the formed by such n variables.

The question is, does there always exist T1,T2 that enable A=T1BT2?

If not, then how to formulate A and B (or add some constraints) so that there always exist T1,T2 that enable A=T1BT2?
