“…Since the publication of this work, various approaches and algorithms have been developed for constructing linearizations of general classes of rational functions/expressions (see, e.g., [9] or [24] for a pedagogical presentation of the subject). For reader's convenience, we provide below a simple linearization algorithm based on the method described in [13,Section A.1]. We use the following observation: for matrices A i ∈ (C x, y, y * ) mi×mi and B j ∈ (C x, y, y * ) mj ×mj+1 , m j ∈ N, the lower right m 1 × m k submatrix of the inverse of the block matrix…”
