Hankel function H(z) of the first or second kind (Real argument, first or second kind, can be scaled.

Syntax
C#
Visual Basic
public static TCplx Besh(double NU, double A, bool Scale, bool FirstKind);
Parameters
Parameters 
Description 
double NU 
describes the order of Hankel function. 
double A 
Defines real value for which H(Z) should be evaluated. 
bool Scale 
If true, the result will be multiplied by scale factor Exp(+i*A) or Exp(-i*A), depending on FirstKind parameter value. 
bool FirstKind 
If true, calculate Hankel function of first kind, if false, calculate Hankel function of second kind. 
Returns

modified Bessel function of the third kind - Hankel function H(A). If parameter FirstKind is true, the return function will be Hankel function of the first kind. If false, the return function will be Hankel function of second kind. If Scale parameter is true, the result will be multiplied by scale factor Exp(+i*A) or Exp(-i*A), depending on FirstKind parameter value.
