gammaln
Logarithm of gamma function
Syntax
R = gammaln(M)
Input argument
M - a real single or real double matrix.
Output argument
R - result of gammaln function.
Description
The function gammaln(A) computes the natural logarithm of the gamma function for a given input A, expressed as gammaln(A) = log(gamma(A)).
It's important to note that A must be a nonnegative real number.
Using gammaln helps prevent potential underflow and overflow issues that might arise if directly computing log(gamma(A)).
Example
R = gammaln([0:0.1:pi])
