i want to make a time-varying system by using Simulink.
And i wanna change the matrix block every loop in time-varying system.
i already know the time-varying matrix at every loop.
ex) M(t)x''+kx=F(t)
the time inverval is 1sec. and stop time is 5 sec.
t=0, M=[0 0;0 0];
t=1, M=[1 0;0 0];
t=2, M=[0 2;0 0];
t=3, M=[0 0;5 0];
t=4, M=[0 0;0 6];
t=5, M=[0 2;0 6];;
i just want to change the M matrix in the Gain block every loop.
or if there is another method to simulate the time-varying system, plz let me know.

You can build the system as you would any other ode. You can use a lookup table to specify M over this time span.
