The moment generating function (MGF) of a random variable, random vector, or random matrix is a function that defines the moments the variable according to its distribution.

Like the PMF or PDF, the MGF of a distribution is unique, meaning that distributions can be characterized by this function.

Definition

Random Matrices

The moment generating function of a symmetric random matrix, denoted ${\Psi }_Q:\mathbb{R}\to {\mathcal{S}}^{d\times d}$, is given by ${\Psi }_Q(\lambda ):={\mathbb{E}}_{}\left[e^{\lambda Q}\right]={\sum }_{k=0}^{\infty }\frac{{\lambda }^k}{k!}{\mathbb{E}}_{}\left[Q^k\right]$
