• Real-valued row vectors for the coefficients of the numerator or
denominator polynomials in the SISO case. List the coefficients in
descending powers of the variable or by default, and in ascending
powers of when the
Variable property is set to 'q' or 'z^–1' (see
note below).
• -by- cell arrays of real-valued row vectors in the MIMO case, for
example,
{[1 2];[1 0 3]} for a two-output/one-input transfer function
• -by- -by- -by- -by- -dimensional real-valued cell arrays for
MIMO LTI arrays
Variable
• String 's' (default) or 'p' for continuous-time systems
• String
'z' (default), 'q',or'z^–1' for discrete-time systems

z, p • Vectors of zeros and poles (either real-valued or complex conjugate pairs of
them)inSISOcase
• -by- cell arrays of vectors (entries are real-valued or in complex
conjugate pairs) in MIMO case, for example,
z = {[],[–1 0]} for a model
with two inputs and one output
