Remark For discrete-time transfer functions, the convention used to represent the

numerator anddenominatordependson the choice of variable (see the

tf entry

for details). Like

tf, the syntax for set changes to remain consistent with the

choice of variable. For example, if the

Variable property is set to 'z' (the

default),

set(h,'num',[1 2],'den',[1 3 4])

produces the transfer function

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,
