摘      要：An algorithm for separating a rational matrix relative to the imaginary axis (the unit circle), that is, for representing it by the sum of two matrices each of which has poles only in the left- or right-hand half-plane (inside or outside the unit circle), is presented. The feasibility Of iterative refinement of the obtained result is demonstrated. The refinement procedure is reduced to the construction of a solution of a system of Sylvester equations. It is shown that the algorithm can be used without a preliminary construction of a minimal realization of the original matrix.
