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...
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\...
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...
Evaluate Gamma Function Evaluate the gamma function with a scalar and a vector. EvaluateΓ(0.5), which is equal to√π. y = gamma(0.5) y = 1.7725 Evaluate several values of the gamma function between[-3.5 3.5]. x = -3.5:3.5; y = gamma(x) ...

The Gamma Function serves as a super powerful version of the factorial function. Let us first look at the factorial function:
Plot Gamma Function Plot the gamma function and add grid lines. syms x fplot(gamma(x)) grid onHandle Expressions Containing Gamma Function Many functions, such as diff, limit, and simplify, can handle expressions containing gamma. Differentiate the gamma function, and then substitute the variable...
The Gamma function is a generalization of the factorial function to non-integer numbers. It is often used in probability and statistics, as it shows up in the normalizing constants of important probability distributions such as the Chi-square and the Gamma. ...
