Hurwitz Matrix

Computes the Hurwitz matrix for a given polynomial. The principal minors are also computed.

H = hurwitz(P) returns the Hurwitz matrix H associated with the

polynomial whose coefficients are specified by P in descending powers.

[H, DELTA] = hurwitz(P) also returns DELTA, a column vector containing

the leading principal minors of H, commonly called the Hurwitz

determinants.

Example:

syms K

P = [1, K, 2, 5];

[H, DELTA] = hurwitz(P)
