We consider the computational complexity of some problems dealing with matrix rank. Let E, S be subsets of a commutative ring R. Let x 1 , x 2 , ..., x t be variables. Given a matrix M=M(x 1 , x 2 , ..., x t ) with entries chosen from E \_ [x 1 , x 2 , ..., x t ], we want to determine maxrank S (M)=
