ss2zp
finds the poles from the eigenvalues of the
A
array. The zeros are the finite solutions to a generalized
eigenvalue problem:
z = eig([A B;C D],diag([ones(1,n) 0]);
In many situations, this algorithm produces spurious large, but finite, zeros.
ss2zp
interprets these large zeros as infinite.
ss2zp
finds the gains by solving for the first nonzero Markov
parameters.
