Function rgsl::bessel::k0_scaled_e

pub fn k0_scaled_e(x: f64) -> (Value, Result)

The irregular modified spherical Bessel functions k_l(x) are related to the irregular modified Bessel functions of fractional order, k_l(x) = \sqrt{\pi/(2x)} K_{l+1/2}(x). This routine computes the scaled irregular modified spherical Bessel function of zeroth order, \exp(x) k_0(x), for x>0.
