Positive Definiteness, Matrix Factorization, and an Imperfect Analogy

1998
The results of this section are purely algebraic, but they will prove to be of great significance in §§13–15 when we discuss linear matrix equations, reachability, and observability, and again in Part in when realization theory for time-invariant input-output systems is treated.
