Does anyone know of a good way to way to integrate ker_2(r), kei_2(r), ker_0(r) and kei_0(r) from r=0 to r=Infinity? can it be done analytically? I'm also a little unsure about how mathematica does this numerically. ker_n(r) + I kei_n(r) = Exp[(-1/2)*n*Pi*I] BesselK[n, Exp[(-1/4)*Pi*I]*r] any help would be greatly appreciated.
