罗德里格公式 Rodrigues' formula

(重定向自Rodrigues formula)

罗德里格公式英语:Rodrigues' formula)是通过对某些函数进行反复的求导以获得一个表达式串行的公式。该公式典型的应用是在正交多项式的推导中,如对于某两个函数W、Q和常数an,能得到以下正交多项式串行:

P_n(x) = \frac{1}{a_n W(x)} \  \frac{d^n}{dx^n}\left(W(x)[Q(x)]^n\right)

此公式由法国数学家欧林·罗德里格最早得出。

Rodrigues' formula 罗德里格公式

(重定向自Rodrigues formula)

In mathematics, Rodrigues's formula (formerly called the Ivory–Jacobi formula) is a formula for the Legendre polynomials independently introduced by OlindeRodrigues (1816), Sir JamesIvory (1824) and Carl GustavJacobi (1827). The name "Rodrigues formula" was introduced by Heine in 1878, after Hermite pointed out in 1865 that Rodrigues was the first to discover it. The term is also used to describe similar formulas for other orthogonal polynomials. Askey (2005) describes the history of the Rodrigues formula in detail.
