隨機矩陣

提示：此條目的主題不是轉移矩陣。

在概率論和數學物理中，隨機矩陣（英語：Random matrix）是一個矩陣值的隨機變量，也就是說，一個矩陣中的所有元素都是隨機變量。^[1]

隨機矩陣模型

設${\displaystyle H}$是${\displaystyle N\times N}$的矩陣，有下面的概率測度：

${\displaystyle P(H)={\frac {1}{Z}}e^{-Ntr(V(H))}}$

例子，高斯模型：${\displaystyle V(H)=H^{2}/2}$。

• GUE (Gaussian Unitary Ensemble)：H是埃爾米特矩陣。通過1/N展開，維格納半圓分佈描述H的大N特徵值的概率密度函數${\displaystyle \rho (E)}$。^[1]
• GOE (Orthogonal)：H是對稱矩陣
• GSE (Symplectic)：H是四元數的矩陣（Quaternion matrix）
