2. Extract the compressed zipped folder “matlab-databricks-v4-0-7-build-…” inside Program Recordsdata MATLAB. As soon as extracted you will notice the “matlab-databricks” folder. Be certain the folders are on this folder and this hierarchy:
   

   

3. Launch the MATLAB utility from native Desktop utility by means of the Search bar and ensure to run as an administrator
   

   

4. Go to the command line interface in MATLAB and sort “ver” to confirm that you’ve got all of the dependencies essential:
   

   

5. Subsequent you’re prepared to put in the runtime on Databricks cluster:
   • Navigate to this path: C:Program FilesMATLABmatlab-databricksSoftwareMATLAB: cd <C:[Your path]Program FilesMATLABmatlab-databricksSoftwareMATLAB>
   • You must see within the prime bar subsequent to the folders icon the present listing path. Guarantee that path appears to be like like the trail written above, and you’ll see set up.m out there within the present folder.
     

     

6. Name set up() from the MATLAB terminal
7. You’ll be prompted with a number of questions for configuring the cluster spin up.
   • Authentication technique, Databricks username, cloud vendor internet hosting Databricks, Databricks org id, and so on
     

     

8. When prompted with “Enter the native path to the downloaded zip file for this package deal (Level to the one in your native machine)”
   • You must present the trail to your MATLAB compressed zip file. E.g: C:UserssomeuserDownloadsmatlab-databricks-v1.2.3_Build_A1234567.zip
9. A job can be created in Databricks routinely as proven beneath (Be certain the job timeout is about to half-hour or larger to keep away from timeout error)
   

   

   a.

   

   b.
