摘要: Van Dooren [Linear Algebra Appl. 27 (1979) 103] constructed an algorithm for the computation of all irregular summands in Kronecker’s canonical form a matrix pencil. The is numerically stable since it uses only unitary transformations. We construct matrices chain linear mappings V1—V2—⋯—Vt andextend Dooren’s to cycle mappings whereall Vi are complex vector spaces and each line denotes → or ←.
