Derivative of bessel functions
WebAug 13, 2024 · My problem is as it says in the title, I am trying to use the derivative (with respect to v) of the modified Bessel function of the second kind K_v(x) but with no success.. I read in one of the documentation that besselDK(v,x) would work as a derivative, apparently this is not a recognized function in R. I tried to use the expansion for the … WebAug 6, 2014 · To differentiate a function numerically, you should use smaller steps and the gradient function: x = 1:0.01:10; J = besselj (1,x); dJ = gradient (J,x); % or: dJ = gradient (J)./gradient (x); plot (x,J,x,dJ) The second numerical derivative can be obtained with dJ2 = 4*del2 (J,x); % or: dJ2 = 4*del2 (J)./gradient (x).^2; plot (x,J,x,dJ,x,dJ2) Share
