I am modelling a simple SIR model. I have modelled the SIR model in Simulink as shown below:
I want to change the beta constant to a variable input but I dont know how to change the input parameter beta to a time-dependent parameter in Simulink?
I know of the function block in Simulink but how do I input 'time' which is days here. We are simulating for 300 days but how do i input the simulation time at the top which is 300 to become an input for the time-dependent beta
Thanks in advance

In the Simulink library browser, on the "sources" pallet, you will find a "clock" function. Use this to create a time signal.
(Note that the output of the clock function is in seconds, so you will need to scale it to get days)
