Matrix multiplication - where two grids of numbers are multiplied together - forms the basis of many computing tasks, and an improved technique discovered by an artificial intelligence could boost ...

For example, multiplying two 4×4 matrices together using a traditional schoolroom method would take 64 multiplications, while Strassen's algorithm can perform the same feat in 49 multiplications.

A matrix is simply a grid of numbers that can represent anything you want. Multiplying two matrices together typically involves multiplying the rows of one with the columns of the other.
