Sure, I can get rid of the word enum. The symbols in the example are numerals for sure, but you explicitly say they're representing colors. I don't know how to multiply colors. What I'm saying is you merely have labels there, the numbers those numerals usually represent have nothing to do with the explicitly stated meaning. If I saw that array without context, yeah sure, I'd assume it's a matrix. But there is context that tells me interpreting this as a transformation makes no sense.

I'm genuinely claiming they aren't numbers due to the explicit context. The entries are colors with numerals as labels.

Now, you've said something slightly different where I think we can agree. If the entries are from a set closed under a notion of multiplication and addition, then it represents a matrix even if it isn't being used in that way. But I still say that if you're merely using the array as a place to keep some data then I won't be using the word matrix, I'll just call it an array.

Anyway. I started this by saying it was interesting that we use the word matrix slightly differently. I still think that's interesting and think it's totally fine if you want to call an array a matrix even if the entries don't come from something where a transformation makes sense. I wouldn't "correct" someone's usage. I just think it's interesting how we use it different. Anyway, I feel like you just think I'm dumb, so I'm ending this here. You might not, but it's hard to read the vibe via text. If you have something to add you think will get me to change my word choices, feel free to respond and I'll read it, but I'm not replying on this thread anymore.
