Overload List
Incomplete | Returns a function that evaluates the Incomplete Gamma function. |
Incomplete | Evaluates the Incomplete Gamma function. |
Incomplete | Evaluates the incomplete Gamma function between two arguments. |
IncompleteGamma(Double)
Returns a function that evaluates the Incomplete Gamma function.
public static Func<double, double> IncompleteGamma(
double a
)
Parameters
- a Double
- A real number.
Return Value
Func<Double, Double>A function that evaluates the incomplete Gamma function with parameter a.
Remarks
The term incomplete here refers to the fact that the integral in the definition of the Gamma function is taken from its second argument onwards instead of from 0.
IncompleteGamma(Double, Double)
Evaluates the Incomplete Gamma function.
public static double IncompleteGamma(
double a,
double x
)
Parameters
Return Value
DoubleThe incomplete Gamma function for x
Remarks
The Gamma function is a generalization to real numbers of the factorial of an integer. If x is an integer, then the following equality holds: \1
The term incomplete here refers to the fact that the integral in the definition of the Gamma function is taken from x onwards instead of from 0.
IncompleteGamma(Double, Double, Double)
Evaluates the incomplete Gamma function between two
arguments.
public static double IncompleteGamma(
double a,
double x1,
double x2
)
Parameters
Return Value
DoubleGamma(a, x1) - Gamma(a, x2).
