Can't open example openExampl​e('stats/T​rainARegre​ssionEnsem​bleExample​')

Hi Matlab buddies,

I can't open example openExample('stats/TrainARegressionEnsembleExample') in my Matlab R2018B. Do you know what the problem could be? The version? I get the following wrong message:

Error using exampleUtils.getExamplesDir (line 13)

Unable to create a working directory at the location returned by the userpath function.

Error in exampleUtils.getWorkDir (line 2)

ed = exampleUtils.getExamplesDir();

Error in setupExample (line 11)

workDir = exampleUtils.getWorkDir(metadata);

Error in openExample (line 29)

workDir = setupExample(id, workDir);

You need to have the "Statistics and Machine Learning Toolbox".

Run "ver stats" to check

I think I have it- this message I get:

Make sure you run the command in a folder that you have write access and can create a subfolder. The command creates a folder \Examples at your current folder.

I have access to the folder and can create a subfolder. I guess the command loads some data? Do I need to load statistic toolbox somehow?

edit exampleUtils.getExamplesDir

Add a breakpoint at line 13, check the condition to figure out which caused the error.
