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

The Unit Delay block delays its input by the specified sample period.
This block is equivalent to the 1/z discrete-time operator. The block
accepts one input and generates one output, which can be either both
scalar or both vector. If the input is a vector, all elements of the
vector are delayed by the same sample period.



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






+ **initial condition** The output of the simulation for the first
  sampling period, during which the output of the Unit Delay block is
  otherwise undefined. Properties : Type 'vec' of size -1.
+ **Inherit (no:0, yes:1)** When "Inherit" is yes, the block inherit
  its event input. Properties : Type 'vec' 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:** dollar
