In numerical analysis, Gauss–Hermite quadrature is a form of Gaussian quadrature for approximating the value of integrals of the following kind: $${\displaystyle \int _{-\infty }^{+\infty }e^{-x^{2}}f(x)\,dx.}$$In this case $${\displaystyle \int _{-\infty }^{+\infty }e^{-x^{2}}f(x)\,dx\approx \sum _{i=1}^{n}w_{i}f(x_{i})}$$where … See more Consider a function h(y), where the variable y is Normally distributed: $${\displaystyle y\sim {\mathcal {N}}(\mu ,\sigma ^{2})}$$. The expectation of h corresponds to the following integral: See more • For tables of Gauss-Hermite abscissae and weights up to order n = 32 see • Generalized Gauss–Hermite quadrature, free software in C++, Fortran, and Matlab See more WebAbstract Although Hermite functions have been studied for over a century and have been useful for analytical and numerical solutions in a myriad of areas, ...

WebFeb 23, 2010 · Generally, a Gauss-Hermite quadrature rule of n points will produce the exact integral when f(x) is a polynomial of degree 2n-1 or less. The value of C in front of the integral depends on the user's choice of the SCALE parameter: scale=0, then C = 1; this is the standard choice for Gauss-Hermite quadrature. Web3D rotation invariants based on orthogonal Gaussian–Hermite moments are proposed in this paper. We present an elegant and easy theoretical derivation of them. At the same time we prove by experiments that the Gaussian–Hermite invariants have better numerical stability than the traditional invariants composed of geometric moments. diy watercolor christmas card ideas
