### 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

- matrix
  A 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

- 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
