The iteration of rational maps is well understood in dimension $1$ but less so in higher dimensions. We study some maps on spaces of matrices which present a weak complexity with respect to the ring structure. First, we give some properties of certain rational maps; the simplest example is the rational map which sends the matrix $\mathrm {M}$ onto $\mathrm {M}^2$ for which we exhibit some dynamical properties. Finally, we deal with some small perturbations of this map.
