Math387.JGamma Method

Math387 Class

Overload List

#SignatureDescription
1TCplx JGamma(Double A, TCplx X)Complement to the incomplete gamma function.
2Double JGamma(Double A, Double X)Complement to the incomplete gamma function.

Overload 1: TCplx JGamma(Double A, TCplx X)

Complement to the incomplete gamma function.

#NameTypeDescription
1ADoublescalar
2XTCplxscalar

Returns: TCplx (complex)

Remarks:

Complex version.

Overload 2: Double JGamma(Double A, Double X)

Complement to the incomplete gamma function.

#NameTypeDescription
1ADoublescalar
2XDoublescalar

Returns: Double - the complement to the incomplete gamma function.

Remarks:

The JGamma function is defined by the following equation:

JGamma(x,a)=1Γ(a)∫x∞ta−1exp⁡(−t)dt=1−IGamma(x,a)\text{JGamma}\left(x,a\right)= \frac{1}{\Gamma(a)} \int _x ^\infty t^{a-1} \exp (-t) dt = 1 - \text{IGamma}(x,a)

where Gamma is Dew.Math.Units.Math387.Gamma function.
