Files have been removed

Hello,

I recently searched my own Mathworks submissions.  Two of them were no longer availaible and a message indicated in both cases, "This file has been removed from File Exchange. Please search File Exchange to find alternative submissions that may fit your need."  I am wondering why the submissions were removed (licensing issue maybe?).  I wanted to make sure to address any issue if there are any.

Previous links to the files were as follow :

Thank you so much for all of your feedback (including helping confirm that I likely inadvertently deleted the submissions myself), and your invaluable help with recovering the original submissions.

I can't say for sure, but they still seem to be there.

I can find all 12 of your submissions on your community profile page.

I resubmitted them this afternoon. I'm still wondering why they had disappeared and if the removal was intented, so I can make modifications if needed. Thank you for having a look. If there are no indications otherwise I will assume I had inavertently deleted the submissions myself.

I prefer to publish my functions with a CC licence, which is not currently allowed on the FEX. I received an email from a staff member (I'm not sure if they would like me to name them). That email listed three options:

1. Moving my submission to GitHub (which allows non-BSD-licences)
2. Edit away the licence statement (effectively changing the CC to BSD)
3. Removing the entire submission

I was not given an ultimatum, but I was warned that without a response my submission would be removed.

Maybe you received such an email, but it ended up in your spam folder?

[C. M. Belanger Nzakimuena]

Thank you so much for your message! To be honest I personally hadn't given much thought to the licenses (I selected MIT everytime when I created git repositories as it was recommended). It might be relevant to add that the removed submissions were on FEX for half a year and I noticed the removal when I began submitting new files this month (which is why it is also possible I inavertently deleted the submissions myself).

I checked and there are no such emails as you described in my spam folder.

Based on your message I reviewed the FAQ page (https://www.mathworks.com/matlabcentral/FX_transition_faq.html). All of my submitted files are linked to GitHub and according to the FAQ, "You can use other licenses if your File Exchange submission is linked to GitHub". I assume then that if my files were removed intentionaly the licenses I specifically selected would not be the issue.

In the case of the submissions that were removed (casForest and PythagoreanForest), they do leverage original and modified versions of other submissions which were availaible on FEX (e.g. Pythagoras tree, generic random forest, etc.). However, this is also true of other files which I submitted and which were not removed. I thought perhaps I missed a requirement when leveraging other licensed work and a modification was needed.

Thank you again for your feedback, much appreciated.

There was an issue that temporarily unpublished a few submissions. Everything has been restored.

Sounds good, thank you very much for the additional information and for resolving the issue.
