SpecialFuncs.Besj Function

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

Pascal

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

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

Returns

the Bessel function of the first kind Jn(Z) with NU parameter describing order of Bessel function. If Scale parameter is true, Jn(Z) is multiplied by factor (see above).
