lngamma¶
Purpose¶
Computes the natural log of the gamma function.
Format¶
-
y =
lngamma(x)¶ - Parameters:
x (NxK matrix or N-dimensional array) – all elements must be positive.
- Returns:
y (NxK matrix) – containing the natural log of the gamma function of each of the elements in x.
Examples¶
x = { 4, 8 };
y = lngamma(x);
y = 1.7917595
8.5251614
Remarks¶
The relation between lngamma() and lnfact() is:
lngamma(x) = lnfact(x - 1);
