Math387::JGamma Function

Math387 Namespace

Overload List

#SignatureDescription
1double JGamma(double A, double X);Complement to the incomplete gamma function.
2TCplx JGamma(double A, const TCplx &X);Complement to the incomplete gamma function.

Overload 1: double JGamma(double A, double X);

Complement to the incomplete gamma function.

#NameTypeDescription
1Adouble
2Xdouble

Returns: 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 Math387::Gamma function.
