The paper is devoted to an algorithm for computing matrices $A^{r}$ and $(A^{r} - I) . {(A - I)}^{- 1}$ for a given square matrix $A$ and a real $r$ . The algorithm uses the binary expansion of $r$ and has the logarithmic computational complexity with respect to $r$ . The problem stems from the control theory.
