MATLAB: In Simulink, How to obtain the -State Vector- from a -Discrete Time State Space- block

Question

The Discrete Time State Space block has only one output which is logically the output of the model to its input, I know it is possible however to also obtain the state vector as part of the output and then use a combination of mux/demux to implement, say, a state observer. Can anyone help me set this up? Thanks in advance!!

Answer 1

If you want to obtain the state vector as an output from your state space model, then you have to set your C matrix like:

C=eye(n);

where n is the number of states in your state space model.
