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

The unique output of this block generates a regular train of events
that are scheduled by parameter **Period** in seconds. The starting
date of events generation can be set in seconds with the
**Initialisation Time** parameter.



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






+ **Period** Scalar. Period is the time that separates two output
  events, it is the inverse of the frequency of the clock. Properties :
  Type 'vec' of size 1.
+ **Initialisation Time** Scalar. Starting date. If negative the clock
  never starts. Properties : Type 'vec' of size 1.




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


+ **always active:** no
+ **direct-feedthrough:** no
+ **zero-crossing:** no
+ **mode:** no
+ **number/sizes of activation inputs:** 0
+ **number/sizes of activation outputs:** 1
+ **continuous-time state:** no
+ **discrete-time state:** no
+ **object discrete-time state:** no
+ **name of computational function:** csuper
