Error using exampleUti​ls.compone​ntExamples​Dir (line 13) Invalid argument "simulink_automotive".

Hello!

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);

I have MATLAB version 2020a by the way.

Hello,

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.

files={'ModelingAnAutomaticTransmissionControllerExample'};
[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!

can you help me

Yo! Make sure you use the latest version of Matlab (or later than the example you want to open) and run the examples you need to see if it works.
