pub fn cached_Inu_Knu(
    nu: f64,
    x: f64,
    cache: &mut HashMap<(u64, u64), (f64, f64)>
) -> (f64, f64)

Cached modified Bessel functions for fractional order

Arguments

• nu - Order of the Bessel function (nu >= 0)
• x - Argument of the Bessel function (x > 0)
• cache - Cache for the Bessel functions (HashMap)

Returns

• I_nu(x) - Modified Bessel function of the first kind
• K_nu(x) - Modified Bessel function of the second kind
