1.在MATLAB中,n的伽马函数可以使用下面的形式访问:x = gamma(n) 例如,Γ(6) = 5! = 120,在MATLAB检验它: >> gamma(6) ans = 120 2.要以表格显示数据,可以在行末包含单引号: >> x = (1:0.1:2)'; 3.MATLAB允许你计算不完全伽马函数(incomplete gamma function),MATLAB中用来求这个函数的命令是:...
3.MATLAB允许你计算不完全伽马函数(incomplete gamma function),MATLAB中用来求这个函数的命令是: y = gammainc(x,n) 当x<<1和n<<1时,不完全伽马函数满足p(x, n) ≈ xn。 4.贝塞尔函数: 在MATLAB中,第一类贝塞耳函数使用besselj实现。调用的形式是:y = besselj(n,x) ...

Matlab functions of functionsI notice you initialize your h to 1. When you follow through the defining formula for incomplete gamma, the t^(a-1) part will become t^0 so that term will vanish, leaving you with an integral from 0 to x of exp(-t) . The integral of exp(-t) is -...

I am trying to do an integration 10000*5 times, it seems like a incomplete gamma function, but it is not, because after i did some changes, the lower limit, in the incomplete gamma function, is (M-i*phi)*epsilon, which is not a real number. Please see the attached file for details...
i=IncompleteGamma%5B0.04344%2C0%5Dand examine them with respect to approaching a = 0, you find that you have a term which is 1 / gamma(0); and since gamma(0) is infinity, 1 / gamma(0) approaches 0, which could lead you to expect that gammainc(x,0) (using lower tail) should...
