Scaling

Enum Scaling 

Source
pub enum Scaling {
    Unscaled,
    Exponential,
}
Expand description

Scaling option for Bessel and Airy function computation.

When Exponential is selected, the result is multiplied by an exponential factor to prevent overflow or underflow. The factor depends on the function type:

  • J, Y: exp(−|Im(z)|)
  • I: exp(−|Re(z)|)
  • K: exp(z)
  • H(1): exp(−iz)
  • H(2): exp(iz)
  • Ai, Ai′: exp(ζ)
  • Bi, Bi′: exp(−|Re(ζ)|)

where ζ = (2/3) · z · √z.
