I think its rather baffling the during the movies the idea was to destroy the matrix and yet if you follow the definition they effectively wanted to destroy the place that they came from.
Any thoughts on this?
In school we learned how to make a repeating roster of plans, which was called a matrix. I found that always very fitting to the reason behind naming the Matrix, "Matrix": A repeating schedule of plans. Here are a lot of definitions of the word, most fit quite well in to the story too.
you also use a matrix in excel >_>
I'm doing discrete maths at the moment and the matrices I'm studying are ones made from spanning trees like this one. Computers use grids to understand these trees and can use algorithms like Prim's algorithm to find the minimum spanning tree. I suppose it's a bit like the Matrix with nodes representing programs and the vertices representing the links between the programs.
