An uncited stub since its creation in 2006. For the most part the term "x-y-z matrix" only appears on mirrors of Wikipedia or in unrelated uses such as XYZ color space or usual 2d matrices transforming a vector whose entries are x, y, z. I found two exceptions,1, 2, which are very brief and confusing. My best guess is that this article is intending to describe an Array data type with 3 indices, but there's no evidence that the term is in common use in that sense.

Delete. The usual names for this object are hypermatrix or tensor (both of which admit higher-dimensional analogues). Unfortunately the most concrete discussion of such things on Wikipedia seems to be at Tensor#As_multidimensional_arrays, which is damn near incomprehensible. (Multilinear_map and Array data type are also relevant, I guess.) There's no substance in this article to merge. The figure is a nice idea but basically unreadable (at least by me). So we have, basically, a made-up term with no citations and no usable content. --JBL (talk) 00:42, 19 September 2021 (UTC)[reply]
Comment this is the classical maths dilemma of Wikipedia. We have an article on tensors that no one can understand unless they already know the subject matter (which seriously undermines the point of having the article). But so far as I know, as a non-mathematician, a tensor doesn't have to be a multi-dimensional matrix, and not all multi-dimensional matrices are tensors?? We have hyper-matrix redirecting to tensor, but another article altogether, Array_data_structure talking about matrices with more than two dimensions. It seems a bit of a mess. It would be lovely if someone could write a comprehensible overview-article on 3-dimensional matrices and their uses. In any case, the current article contains no useful information, and it isn't the natural name for the overview-article I'd like to see. Elemimele (talk) 11:33, 19 September 2021 (UTC)[reply]

You are correct that multidimensional matrices and tensors are different things. Poiu45 (talk) 05:35, 20 September 2021 (UTC)[reply]

Delete The subject matter is legitimate, but the name is not, and there's no useful content for merging. The name people actually use for this thing is just tensor. Tercer (talk) 11:57, 20 September 2021 (UTC)[reply]
Delete Not a name that anyone actually uses for three-dimensional arrays or tensors represented by them. None of the content is worth merging. XOR'easter (talk) 16:06, 20 September 2021 (UTC)[reply]
Delete Per other responses. Concept is already described in other articles, and neither scholarly nor popular sources appear to talk about the subject as a standalone mathematical concept. No content worth merging. AviationFreak💬 18:18, 20 September 2021 (UTC)[reply]
