Let $\mathcal{E}$ be the $\sigma$-ideal generated by the closed measure zerosets of reals. We use an ultrafilter-extendable matrix iteration of ccc posetsto force that, for $\mathcal{E}$, their associated cardinal characteristics(i.e.\ additivity, covering, uniformity and cofinality) are pairwise different.

A friendly iteration forcing that the four cardinal characteristics of $\mathcal{E}$ can be pairwise different
