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

This block counts with an increment/decrement value equal to one from
**Minimum** to **Maximum** or from **Maximum** to **Minimum**
depending on the choice of the **Rule** parameter.



Data types
~~~~~~~~~~


+ Output: scalar double.




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






+ **Minimum** The lowest number of the counter. Properties : Type
  'vec' of size 1.
+ **Maximum** The highest number of the counter. Properties : Type
  'vec' of size 1.
+ **Rule (1:Increment, 2:Decrement)** The rule of counting :

    + **1**: Counts from the lowest number to the highest number. The
      count is increasing.
    + **2**: Counts from the highest number to the lowest number. The
      count is decreasing.
  Properties : Type 'vec' of size 1.




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


+ **always active:** no
+ **direct-feedthrough:** no
+ **zero-crossing:** no
+ **mode:** no
+ **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:** counter
