## Matrix

You may have heard the term ‘matrix’ from Doctor Who and the film series called ‘The Matrix’. Some of us even remember matrices from school. Anyone fascinated with organizing will immediately appreciate the idea of a matrix intuitively, even if we cannot spend time on a holodeck like in Star Trek.

A Matrix is a rectangular array of numbers symbols arranged in rows and columns. The individual items in a matrix are called its elements or entries. Matrices are found in most scientific fields, including many branches of physics. Matrices are used to study physical phenomena, such as the motion of rigid bodies. In computer graphics, matrix applications are used to project a 3-dimensional image onto a 2-dimensional screen. Statistical matrices (Stochastic) comprise probability sets; as used in internet search algorithms. Matrix calculus generates classical derivatives and exponentials to higher dimensions. Finding efficient algorithms for matrix computations is part of the expanding field of numeric analysis.

Matrices chart the fabric of physical reality, and create artificial worlds of the imagination as well. Whether we are escaping or investigating, we often use matrix technology in our daily lives. The complex concept of matrix is akin to what Sartre called ‘the simulation of the simulacra’ in post-modern philosophy.
