With respect to following post I have some doubts related to command get_param:
1) When I use this command it returns me empty vector. 2) Can we use this command for any block like display, demux and out or it has to be Gain block only?
Thanks Mitesh

I believe it can be done that way and it should apply to all types of blocks. Remember you can't just use get_param() alone, you need to set up the event listener and callback function. See Guy Rouleau's anser in this post. It points to the link from the Mathworks website.

My understanding is, whenever the event happened, the pre-defined callback function will be executed.

- When you use get_param where? what block and what code?
- That command can only get the parameters supported by the block you are using as argument.

You first have to start simulation, and right after that you can add eventlisteners.

Another solution would be to use a Matlab function in your model to update the GUI handle in each timestep. Pass the value from model which needs to be displayed in GUI and update GUI handle respectively.

Another posible solution is using another block instead of a "Gain" block. i used a "Product" and worked like it was a "Gain" block. rto = get_param('lm35_sim/Product','RuntimeObject');
