If a transfer function Y is expressed in MATLAB as a ratio o

If a transfer function Y is expressed in MATLAB as a ratio of factors in the numerator and denominator, which command can be used to convert to a transfer function expressed as coefficients in the numerator and denominator? tf(Y) zpk(Y) zp2tf(Y) tf2zp(Y)

Solution

Zp2tf command is used for this conversion

[Num,den]=zp2tf(Z,P,K) forms the transfer function.

Set of zero locations are in vector Z,set of pole locations are in vector P,gain in K
