[Academic integrity] Can a PDF exported from MATLAB (and not subsequently modified) ever have "PSPDFKit" for "PDF Producer"?
This past semester, I gave students homework assignments whose completion requirements included creating or modifying .mlx files, running them, exporting a PDF, and submitting that PDF electronically. I suspect that some of the submissions were created in a way that did not comply with course policy, in one fashion or another, and have noticed that the metadata (as viewed using "Document Properties" in Acrobat) for some of these include "PDF Producer: PSPDFKit." I'm not familiar with PSPDFKit, but a bit of googling suggests a couple different possible uses that would be out of compliance. So I wanted to check: Is there any plausible set of conditions (e.g., the right combination of MATLAB version, OS, OS version, and other software installed) under which MATLAB could export a PDF with that property?
