do you know the difference between set and set_param

set

[bo peng]

get function can get the parameter of block, get_paramer have the same function, what is the difference of them.

identical, do you know the difference between set and set_param

Answer 1

[Steven Lord]

The set_param function is intended to set parameters of Simulink models and Simulink blocks.

The set function is intended to set properties of certain types of MATLAB objects. Most commonly it is used to set properties of Handle Graphics objects like line handles, axes, and figure windows but class authors can write their classes so users of those classes can interact with them using set and get.

The two functions are not interchangeable as far as I'm aware.

In my experience, when the first input to set is a block handle, it works just as set_system. set has the advantage over set_param, that you can set the same property on multiple blocks at once. set_param only uses the first handle when you pass multiple into it.

@Julian Hapke

Can you link to the documentation that shows this usage of set with multiple handles to blocks?

Also, is there a doc page for set_system? I can't find it in my release R2022a.

I'd like to read about both.

[Julian Hapke]

I don't know any command named set_system. I don't know if using set for Simulink Blocks is documented, I just tried it and it worked. I used it just like I would when dealing with graphic handles: set(array_of_handles, 'Property', Value)
