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

• 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
