gammaLog

gammaLog(double x)

Description

Returns the natural logarithm of the gamma function of x:
ln(Γ(x)).
The gamma function is an extension of the factorial function that works on all positive values of x.
If n is a positive integer, then: Γ(n) = (n - 1)!.

The gammaLog function may be useful in System Dynamics models for computing combinatorial factors.

Parameters

Name Type Description
x double the value.

Result

Type Description
double ln(Γ(x))
