Finding solution to Mv=v over $\mathbb{Z}$={0,1} for matrix M given a set linearly independent v

It is not possible. Such matrices don't exist. We always have $Mv=v$ whenever $v=0$ (the all-zeros vector). No set that contains the all-zeros vector is linearly independent, so surely $0 \notin V$....
