gamma function的更多可爱性质 由定义式出发不难证明伽马函数在自变量取正整数时的值,例如 \Gamma(1)=\int_{0}^{\infty}e^{-t}\mathrm{d}t=1 进而利用基本递推性质得到 \Gamma(n+1)=n!\quad(n=0,1,2,\cdots) 伽马函数在自变量取零和负整数时是没有定义的,这意味着 \Gamma(-n)\rightarrow\...
1、什么是gamma函数 伽玛函数(Gamma Function)作为阶乘函数(严格上是f(x)=(x-1)!)的延拓,是定义在复数范围内的亚纯函数,通 常写成Γ(x),负整数和0是它的一阶极点。 在实数域上对(x-1)!的延拓 (1)在实数域上gamma函数定义为: Γ(x)=∫0+∞tx−1e−tdt(x>0) 实数域上的gamma函数 (2)在复...

The (complete) gamma function is defined to be an extension of the factorial to complex and real number arguments. It is related to the factorial by (1) a slightly unfortunate notation due to Legendre which is now universally used instead of Gauss's simpler (Gauss 1812; Edwards 2001, p...
The Gamma Function serves as a super powerful version of the factorial function.Let us first look at the factorial function:The factorial function (symbol: !) says to multiply all whole numbers from our chosen number down to 1. Examples: 4! = 4 × 3 × 2 × 1 = 24 7! = 7 × 6...

In mathematics, the gamma function (represented by the capital Greek letter Γ) is an extension of the factorial function, with its argument shifted down by 1, to real and complex numbers. That is, if n is a positive integer: [Math Processing Error] ...
1、为什么需要伽玛函数？因为我们要泛化阶乘！阶乘函数仅针对离散点（对于正整数-上图中的黑点）定义，但是我们希望连接黑点。我们想将阶乘函数扩展到所有复数。阶乘的简单公式x！=1*2…x，不能直接用于小数值，因为它仅在x是整数时才有效。因此，数学家一直在寻找...“什么样的function将这些点平滑地...
