 where **A0**, **A1**, ..., **Ar** are matrices which elements are power series of **x**. One of possible form of them is **Sum(f(k)*x^k, k = 0 .. ∞)** where **f** is a Maple operator/procedure of an integer argument. It computes the coefficients of **x^k**.  where **A0**, **A1**, ..., **Ar** are matrices which elements are power series of **x**.
