Re: Proposal: Add new 'Matrix' object
A matrix could be viewed as an array of arrays or sets or maps or other values. How the values in the arrays or indexes are mapped is dependent upon the requirement. The requirement could be to map the networks of this entire planet earth; create sets of permutations; create cross word puzzles. What is the basic functionality of the Matrix described at this proposal?

Re: Proposal: native XML object support.
I prefer JSON over XML any time but the only area where JSON can't compete with XML is UI.

Re: Proposal: native XML object support.
Thanks for reply. Didn't know that it existed before! I don't think we can say that we live in a JSON centric world when things like React show up and revolutionize web development. I think JSON has its uses and XML has its uses. UI shouldn't been ever seperated from controller since one can't exist without the other.

Proposal: native XML object support.
Hello, I am proposing to support XML object native in JavaScript so the following code would be possible let foo = Which creates an object called foo with name = "input" and value = "Ok", children = null, and constructor = null `constructor` property would include a constructor to be called when a new XML object is created. While `childern` would include any inner XML items inside the XML element. It's nature to support XML as object natively next as JSON format is already supported natively. Supporting XML would open new possibilities notably in the UI side as we would be able to merge UI with Controller logic code. This is similar to React framework.

Re: Proposal: Add new 'Matrix' object
is that a tentative "no" as in tc39 can't easily spec some low-level linear-algebra primitives that would be useful for both dommatrix, and [gpu-accelerated] tensoflow? i do find value to industry for enhancing client-side performance of 3d visualization and ML. and i'm starting to see @Ed's original question as whether things like this falls in the scope of javascript language-design (as a fundamental UX-workflow problem), or should remain an embedder/userland concern. -kai On Mon, May 13, 2019 at 3:34 AM David Teller wrote: > According to the specs, DOMMatrix is limited to 4d matrices.

Re: Proposal: Add new 'Matrix' object
According to the specs, DOMMatrix is limited to 4d matrices. They can be used to emulate 1d-3d matrices trivially. However, many applications (e.g. in graph theory) require arbitrary numbers of dimensions. I'm not really familiar with Tensorflow, but if I read the API correctly, it seems to be limited to 1d-5d tensors. If I read the API correctly, arithmetic operations are tensor operations, rather than matrix operations, which have very different definitions.
