Special.Bessel
Evaluates the Bessel functions of the first and second kind of real order
and complex argument scaled to remove the exponential factor along the imaginary axis.

A 2-tuple with the value of the Bessel function of the first and second kind of order nu at z.

public static (Complex<double> , Complex<double> ) BesselJYScaled(
double nu,
Complex<double> z
)Parameters
- nu Double
- A real number that specifies the order of the Bessel functions.
- z Complex<Double>
- The value at which to evaluate the Bessel functions.
Return Value
ValueTuple<Complex<Double>, Complex<Double>>A 2-tuple with the value of the Bessel function of the first and second kind of order nu at z.
Remarks
The Bessel functions of the first kind increase exponentially as the imaginary part of the argument increases. This function returns the Bessel function of the second kind scaled by a factor of exp(-|Im(z)|) to remove this exponential factor.
