MATLAB: “Icon” file in GitHub-managed MATLAB Project

githubMATLABprojectversion control

I am new to both "Projects" and collaborating via GitHub.

In the past few months, I turned an existing project into a Project and later put it under GitHub source control so that a student can begin merging in her contributions.

Somewhere along the way there appeared in the project directory called Icon. It appears in the directory listing on the left of the MATLAB window, and it has a green dot to indicate that it's up-to-date in Git. When I look in the Finder on my Mac, I see no such file. A directory listing using ls -l at the terminal returns:

-rw-r–r–@ 17 roy staff 0 Nov 18 02:50 Icon?

That puts the date as yesterday, which is weird, since I haven't touched the project in a few weeks, and it doesn't help me figure out whether this is related to the Project or to Git/GitHub.

The student is also new to Projects and GitHub. She downloaded the project, made some modifications, and tried to commit her changes within MATLAB. She got the error message

error: invalid path 'Icon?'

fatal: make_cache_entry failed for path 'Icon?'

So, lots of questions.

What is Icon?
Was it created when I created the project or when I put it under version control?
Can I get rid of it?

Thanks

I had not been actively editing so I was on the main branch. I just created a branch to experiment with removing this file and am testing to make sure that this doesn't break anything.

MATLAB: Can I directly upload matlab output to github repistory

One potential way to automatically upload files to GitHub is to include "git" commands within the scripts generating the output files to automate the process of committing and pushing these files to your git repository.

To do so, the script would need to run within a directory which has been set up to use Git source control and linked to the desired GitHub repository. If this has not already been done, it can be accomplished by right-clicking in the "Current Folder" browser and selecting "Source Control > Manage Files..." and then following the prompts.

Then, in the desired script, you will add the "git" commands needed to upload the generated files. As MATLAB does not have built-in "git" commands, you will need to use the "!" symbol to instruct MATLAB to run them as operating system commands. For example, if you generate the file "file1.m" and want to upload it to the GitHub repository, you could add the following commands:

!git add file1.m
!git commit -m "added file1.m"
!git push

MATLAB: How to create a Simulink Project under Source Control (Git) and upload it on a remote repository (GitHub)

1. Open Simulink Project (PRJ file)

2. Click on 'Use Source Control' and 'Add Project to Source Control'

3. Change Source Control Integration to 'Git', select your local Project root, and Click on 'Convert'

4. Click on 'Open Project'

5. In Simulink Project, go to the 'Modified Files' view and click on Commit (you can enter any comment), then click on 'Submit'

6. Under the Simulink Project tab, go to 'Share' and select 'GitHub'

7. Enter your GitHub credentials and add any Repository Name. Then, click on 'Create', and then 'Yes'

8. Click on 'Reload Project'

If you then would like to create a new branch and push it:

9. In the Simulink Project tab, click on 'Branches'

10. In the 'Branch and Tag Creation' pane, enter 'SecondBranch' as 'Name', and then 'Create'

11. From the dropdown menu in the Branch Browser, select 'SecondBranch', then 'Switch', and then 'Close'

12. In the Simulink Project tab, now click on 'Push' and enter your credentials
