bessel_K_exp_integ_tl
¶ Exponentially scaled modified Bessel function of the second kind by integration.
This class uses an integral representation of the exponentially scaled modified Bessel function of the second kind
\[ K_n(z) e^{z} = \frac{\sqrt{\pi} z^{n}}{2^{n} \Gamma(n+1/2)} \int_1^{\infty} e^{z(1-t)} \left(t^2-1\right)^{n-1/2}~dt \](see http://functions.wolfram.com/Bessel-TypeFunctions/BesselK/07/01/01/)Public Functions
