A positive-definite matrix which is not extendible

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1984
This note treats the problem of extendibility of a positive-definite matrix. The difference between extendibility and positive- semidefiniteness in multiple dimensions is described. The construction of a positive definite nonextendible correlation matrix is also given.

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.
