I know that I am facing this issue due to me not installing the correct toolbox. I am trying to open the example given by the Matlab Command "openExample('simulink_automotive/ModelingAnAutomaticTransmissionControllerExample')". But I am unsure of which one that I need to install so that I can open the example of
Modeling an Automatic Transmission Controller.
Can you let me know which one is the toolbox that I need to install? I have both stateflow and simulink installed. This is the exact error message I am getting.
Error using exampleUtils.componentExamplesDir (line 13)
Invalid argument "simulink_automotive".
Error in findExample (line 18)
componentExamplesDir = exampleUtils.componentExamplesDir(component);
Error in openExample (line 30)
metadata = findExample(exampleId);

From my understanding, the above mentioned error occurs when a toolbox required to open a model is not installed.
The dependencies.toolboxDependencyAnalysis(files) gives a cell array of the toolbox names required by the files in the argument 'files'. These are the toolbox names for the model you mentioned.
[names, folders] = dependencies.toolboxDependencyAnalysis(files)
names =
1×4 cell array
{'MATLAB'} {'Simulink'} {'Simulink Coder'} {'Stateflow'}
folders =
1×4 cell array
{'matlab'} {'simulink'} {'simulinkcoder'} {'stateflow'}
Since you mentioned you have 'Simulink' and 'Stateflow' installed, you may have to install 'Simulink Coder'.
Hope this helps!

Hi! I got the solution. I have Simulink Coder installed as well. The issue is that this example is made using MATLAB 2020b. I was able to open the example in MATLAB Online and export it to the 2020a version from there. Thank you for your response!
