SpecialFuncs.Besi Function

Modified Bessel function of the first kind In(A) (Real argument, can be scaled).

Pascal

function Besi(NU: double; A: double; Scale: boolean): TCplx; overload;

Parameters	Description
NU	Defines the order of the Bessel function of the first kind In.
A	Defines real value for which In(A) should be evaluated.
Scale	If Scale parameter is true, In(A) is multiplied by exp(-\|Re(A)\|).

Returns

the modified Bessel function of the first kind In(A), with NU parameter describing order of Bessel function.If Scale parameter is true, Kn(A) is multiplied by appropriate factor (see below).
