Description
~~~~~~~~~~~

This block realizes a SISO linear system represented by its rational
transfer function (in the symbolic variable z). The rational function
must be proper.



Dialog box
~~~~~~~~~~






+ **Numerator (z)** This parameter sets the numerator of the transfer
  function. This must be a polynomial in **z** . Properties : Type 'pol'
  of size 1.
+ **Denominator (z)** This parameter sets the denominator of the
  transfer function. This must be a polynomial in **z** . Properties :
  Type 'pol' of size 1.




Default properties
~~~~~~~~~~~~~~~~~~


+ **always active:** no
+ **direct-feedthrough:** no
+ **zero-crossing:** no
+ **mode:** no
+ **regular inputs:** **- port 1 : size [1,1] / type 1**
+ **regular outputs:** **- port 1 : size [1,1] / type 1**
+ **number/sizes of activation inputs:** 1
+ **number/sizes of activation outputs:** 0
+ **continuous-time state:** no
+ **discrete-time state:** yes
+ **object discrete-time state:** no
+ **name of computational function:** dsslti4
