Where do I find files for simulink tutorials?

For example in https://www.mathworks.com/help/simulink/gs/navigate-model.html it refers to a smart_braking model. This model does not exist in my install.

open_system(fullfile(matlabroot,'help', 'toolbox', 'simulink', 'examples', 'smart_braking')) 'C:\Program Files\MATLAB\R2018a\help\toolbox\simulink\examples\smart_braking' is not a valid Simulink object name and no matching file found.

in the doc page

Answer 1

[Fangjun Jiang]

That web page is for R2018b document. What are you looking for? For Simulink tutorial in your version, type

web(fullfile(docroot, 'simulink/getting-started-with-simulink.html'))

[Steven Lord]

I believe that documentation page and the model it uses were added to demonstrate the simplified interface enhancements introduced in release R2018b for navigating your model.
