ssdata

Access state-space model data.

Syntax

  • [A, B, C, D] = ssdata(sys)

  • [A, B, C, D, Ts] = ssdata(sys)

Input argument

  • sys - LTI model.

Output argument

  • A - State matrix: Nx-by-Nx matrix.

  • B - Input-to-state matrix: Nx-by-Nu matrix.

  • C - State-to-output matrix: Ny-by-Nx matrix.

  • D - Feedthrough matrix: Ny-by-Nu matrix.

  • TS - Sample time: scalar.

Description

The function ssdata(sys) retrieves the matrix data A, B, C, D from the state-space model (LTI array) represented by sys.

If sys is initially in the form of a transfer function or zero-pole-gain model (LTI array), it is automatically converted to the state-space representation before extracting the matrix data.

Example

sysIn = ss([1 0;0 -2], [-1;0], [2 1], 0, 3.2);
[a, b, c, d, Ts] = ssdata(sysIn)
