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

• regular inputs:

  - port 1 : size [1,1] / type 1

• regular outputs:
