simulink open_system

i can open a simulink file with
"open_system" command.

I want to see if the simulink model is opened?
how can i check whether the mdl file is opened or not?

thank you.

openModels = find_system('SearchDepth', 0)

openModels will be a cell array of all the currently opened models. You can
use the STRCMP function on openModels to check wheter a particular model is
open.

Try "bdIsLoaded"

I added a little more to this with the following blog post:
