gammainc(z,nu) = 1 - igamma(nu,z)/gamma(nu)represents the regularized lower incomplete gamma function in terms of the upper incomplete gamma function. igamma(nu,z) = gamma(nu)*(1 - gammainc(z,nu))represents the upper incomplete gamma function in terms of the regularized lower incomplet...
Calculate the regularized lower incomplete gamma function fora= 0.5, 1, 1.5, and 2 within the interval0≤x≤10. Loop over values ofa, evaluate the function at each one, and assign each result to a column ofY. A = [0.5 1 1.5 2]; X = 0:0.05:10; Y = zeros(201,4);fori = 1:...
Some properties of the regularized lower incomplete gamma function are: limx→∞P(x,a)=1 for a≥0 limx,a→0P(x,a)=1 Tips When the regularized upper incomplete gamma function is close to 0, specifying the'upper'option to calculate the function is more accurate than subtracting the ...
