I apologize if this is in the wrong forum, but I'm not quite sure there's a category where this would fit in.(adsbygoogle = window.adsbygoogle || []).push({});

Anyway, I'm doing an independent research/analysis of the RGB color space, and as I'm writing down my formulas and algorithms, I want to express in the math that certain variables are arrays, and in some cases, array vectors.

My question is, is there any notation specifically for arrays? What I've been using to mark the vectors that are arrays, is putting an x and y on the left side of the vector, like a division problem, just without the line in between.

If there isn't any notation used in any formal math subjects, would this be an acceptable method, as long as it's stated in the report?

Thanks!
