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

This block realizes a discrete-time linear state-space system. The
system is defined by the matrices and the initial state . The
dimensions must be compatible. At the arrival of an input event on the
unique input event port, the state is updated.



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






+ **A matrix** square matrix. Properties : Type 'mat' of size [-1,-1].
+ **B matrix** The matrix, [] if system has no input. Properties :
  Type 'mat' of size ["size(%1,2)","-1"].
+ **C matrix** The matrix , [] if system has no output. Properties :
  Type 'mat' of size ["-1","size(%1,2)"].
+ **D matrix** The matrix, [] if system has no D term. Properties :
  Type 'mat' of size [-1,-1].
+ **Initial state** A vector/scalar initial state of the system.
  Properties : Type 'vec' of size "size(%1,2)".




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

+ **zero-crossing:** no
+ **mode:** no
+ **regular inputs:** **- port 1 : size [1,1] / type 1**
