'''Matrix model''' may refer to:
== Mathematics and physics ==
* a model using a [[Matrix (mathematics)|matrix]] in mathematics
* 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]].
* [[Matrix models (physics)]], a simplified quantum gauge theory and related mathematical techniques used to study a wide range of topics in theoretical and mathematical physics
* The "old" matrix models are relevant for [[string theory]] in two [[spacetime]] dimensions. The "new" matrix model is a synonym for "[[Matrix theory (physics)|matrix theory]]."
* [[Matrix theory (physics)]], a quantum mechanical model
* A concept from [[algebraic logic]].
* [[Matrix population models]] , area usedtype toof population model wildlifethat anduses human populationmatrix dynamics.algebra▼* [[Matrix management]], an organizational structure
==See Biomedicine also==
* [[Matrix (disambiguation)]]
▲* [[Matrix population models]] are used to model wildlife and human population dynamics.
* [[Algebraic logic]]
* 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.
* [[Complete graph]]
* Protein complexes: a 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]].
* [[Lax pair]]
* [[String theory]]
== Management and economics ==
* The term "matrix model" is used to describe [[matrix management]] where each worker in an organisation has two managers, one "functional": managing their expertise, the other "executive": managing their work on a project.
