zpk2tf

Zero pole gain to transfer function

Syntax

S = zpk2tf(sys)

Arguments

sys

A linear dynamical system in zero-pole-gain representation (see zpk).

S

The rational transfer function representation of sys.

Description

Converts a zero pole gain representation to rational transfer function

Examples

sys = zpk([2;1], [0;-3-%i;-3+%i], 2.5, "c")
typeof(sys)

S = zpk2tf(sys)
typeof(S)
        --> sys = zpk([2;1], [0;-3-%i;-3+%i], 2.5, "c")

        sys = [zpk]
       
               (s-2) (s-1)  
          2.5 ------------- 
              s (s^2+6s+10) 
       
       
       --> typeof(sys)
       
        ans = 
       
         "zpk"
       
       --> 
       
       --> S = zpk2tf(sys)
       
        S = [rational] of s
       
          5 -7.5s +2.5s^2  
          ---------------  
          10s +6s^2 +s^3   
       
       --> typeof(S)
       
        ans = 
       
         "rational"
