Web14 sep. 2024 · Asymptotic stability of the polynomial or dynamical system is strongly connected with Schur matrices and Schur's theorem. A Schur matrix is a square matrix with real entries and with eigenvalues (cf. also Eigen value) of absolute value less than one [Bh] , . Schur's theorem states that every matrix is unitarily similar to a triangular matrix. Web1 jan. 2012 · Don't invert the matrix. Almost always, the thing you're using the inverse to accomplish can be done faster and more accurately without inverting the matrix. Matrix inversion is inherently unstable, and mixing that with floating point numbers is asking for trouble.
