母函数 Generating function(重定向自Generating functions)
在数学中,某个串行 母函数可分为很多种,包括普通母函数、指数母函数、L级数、贝尔级数和狄利克雷级数。对每个串行都可以写出以上每个类型的一个母函数。构造母函数的目的一般是为了解决某个特定的问题,因此选用何种母函数视乎串行本身的特性和问题的类型。 母函数的表示一般使用解析形式,即写成关于某个形式变量x的形式幂级数。对幂级数的收敛半径中的某一点,可以求母函数在这一点的级数和。但无论如何,由于母函数是形式幂级数的一种,其级数和不一定对每个x的值都存在。

Generating function 母函数(重定向自Generating functions)
In mathematics, a generating function describes an infinite sequence of numbers (an) by treating them like the coefficients of a series expansion. The sum of this infinite series is the generating function. Unlike an ordinary series, this formal series is allowed to diverge, meaning that the generating function is not always a true function and the "variable" is actually an indeterminate. Generating functions were first introduced by Abraham de Moivre in 1730, in order to solve the general linear recurrence problem. One can generalize to formal series in more than one indeterminate, to encode information about arrays of numbers indexed by several natural numbers. |
