The Matrix
There's nothing here to point as to why this name was given to a 1999 film (it wasn't just plucked from nowhere) and used too in Doctor Who, and why such a structure is different to a vortex for instance.

 * Well, that would be Matrix in the first instance, and secondly we don't usually include words from 'fictional universes' because they're purely creations of their author rather than dictionary word. Appendix:Doctor Who would be valid. Mglovesfun (talk) 16:04, 5 October 2010 (UTC)

Dimensionality
Strictly speaking, in Mathematics and Computers, Matrices are not limited to 2 dimensional (rectangular). They can have any dimentionality greater than zero. A one-dimensional matrix is called a vector. Three-dimensional matrices are very common. Four and five dimensions occur from time to time. And so on.
