— Function File: tf2sys (num, den, tsam, inname, outname)

Build system data structure from transfer function format data.

Inputs

num

den

Coefficients of numerator/denominator polynomials.

tsam

Sampling interval; default: 0 (continuous time).

inname

outname

Input/output signal names; may be a string or cell array with a single string entry.

Output

sys

System data structure.

Example

          octave:1> sys=tf2sys([2 1],[1 2 1],0.1);
          octave:2> sysout(sys)
          Input(s)
          1: u_1
          Output(s):
          1: y_1 (discrete)
          Sampling interval: 0.1
          transfer function form:
          2*z^1 + 1
          -----------------
          1*z^2 + 2*z^1 + 1
