logfactorial.m

Logarithm of the factorial function. Avoids complications with factorials of large numbers overflowing 64-bit numbers.

Syntax

    lf=logfactorial(n)

Parameters

    n - non-negative integer number

Outputs

    lf - logarithm of the factorial of n

Notes

Double precision overflow is a persistent problem with Clebsch-Gordan coefficients and other objects that involve factorials.
