Hi Masa,

You are getting this error because MATLAB is not able to find the "helperDownloadData" function. You can remove this error by either creating a function file for this or adding the function definition at the end of your script; the function definitions of all the support functions are given at the end of the documentation page. For your reference, I'm attaching a direct link for the support functions mentioned in the documentation page. FYI I was able to run the example successsfully directly.

Hope this helps you to proceed with your workflow.
