Research output: Contribution to JournalArticleAcademicpeer-review


We consider the problem of parametrizing the set of nonsquare minimal spectral factors of a rational matrix function taking positive semidefinite values on the imaginary axis. The tool here is the use of factorizations of a certain type of the function W
