MATLAB: Simulink Mux parameters

Question

Hi,

I trying to use the value of Mux block output(2 in –> 1 out) in a .m file(my program). I´ve try 'get_param' with parameter 'Value' without success. What the right parameter to read the value in my program. I´m expecting that the value is a vector with 2 elements.Right ?

Thanks Eric

It is not particularly related to the Mux block. You are looking for a way to get the dynamic signal data from a Simulink block while the simulation is running. See this post http://www.mathworks.com/matlabcentral/answers/14061-get-value-from-simulink-model-to-matlab-gui-while-simulink-is-running for the method. There are several steps involved. See link from TMW.

I would recommend that you not to get the signal data from the Mux block. Instead, you should try to get the signal data from its source, such as a Gain block, or a Sum block where the signal is created. Mux block in many cases is used for signal routing.
