* In [[theoretical physics]], a '''matrix model''' is a system (usually a [[quantum mechanics|quantum mechanical]] system) with [[matrix (math)|matrix]]-valued [[physical quantity|physical quantities]]. See, for example, [[Lax pair]].

* The "old" matrix models are relevant for [[string theory]] in two [[spacetime]] dimensions. The "new" matrix model is a synonym for "[[Matrix theory (physics)|Matrixmatrix theory]]."

* A concept from [[Algebraicalgebraic logic]].

== Biomedicine ==

* [[Matrix population models]] are used to model wildlife and human population dynamics.

* [[The [[Matrix Model]] of substance abuse treatment]] is a model developed by the Matrix Institute on Addictions in the 1980s to treat [[cocaine]] and [[methamphetamine]] addiction.

* Protein complexes: Aa matrix model of protein complexes (unrealistically) predicts that all proteins in a complex interact with all other proteins. Mathematically, a matrix model of a protein complex is a [[complete graph]].

== Management and economics ==

* The term "Matrixmatrix model" is used to describe [[Matrixmatrix management]] where each worker in an organisation has two managers, one "functional": managing their expertise, the other "executive": managing their work on a project.
