Discrete sampling on continuous-time model

Hello,
For an assignment I have a model in simulink. The model is a statefeedback model in continuous time. Because the system itself uses a computer to control the system I need to control part to be discrete, while the model is continuous.
For the input I achieved it by using the zero-order hold. However I also need to sample the state before it is multiplied by the feedback matrix K. How can I sample the state(where Scope2 measures)? I tried to also use a zero-order-hold, but this gave errors, due to the dimensions. Using a mux and demux does not solve this problem. Regards, Jan Jaap

If your are working with continuous system, why are you using sample time, The numeric problem is handled by your solver

Have you tried to set the sample time of your Gain2 block?
