I want to change the system matrix during the dynamic simulation within the Simulink. I can do that with following codes using the command "lsim": ..... %%Stage I X1 = lsim(sys_1,u(1:100),t(1:100)); %%Stage II X2 = lsim(sys_2,u(101:end),t(101:end),X1(end,:)); %%X1(end,:) is the last state of Stage I and to be the initial state of Stage II .....

But for convenient, I prefer the simulation to be performed in the Simulink with the block "State-space". How could I to integrate the above two lsims into one Simulink model with some special design and blocks?

Thank you!
