How can I pass GUI data to simulink?

I'm designing a GUI to calculate PID parameters using Ziegler-Nichols, Cohen_Coon and so on. This GUI calculate the parameters and display it, I'd like to send the result values to a PID Controller block on simulink. I'v read about set_param function but I don't know how to use it actually.

the best way is set_param, and it's simple
if your moel name is 'ModelName', and an PID Controller name is 'PID Controller' (name by default) then if your parameters are Kp, Ti ad TD
set_param('ModelName/PID Controller','P',num2str(Kp)) %Proportional action
set_param('ModelName/PID Controller','I',num2str(Ti)) %Integral action
set_param('ModelName/PID Controller','D',num2str(Td)) %Derivative action
