Interesting, though I think I would put those examples under a “will emit copyrighted code if prompted to”. I can’t think of a compelling reason someone would prompt for a sparse matrix function with a “cs_” unless they were searching for copyrighted code they knew existed.

Though that is definitely a simpler prompt than I would have expected was necessary to get such a result. Thanks!

(The first example also isn’t the same code. It is very close, and definitely similar in style, but it isn’t clear that code would a)run, or b) would work as expected. I need to sleep though, so I’m not sure how much that matters.)
