gammaln(X,Y) returns the logarithm of the gamma function for arguments X and Y'.

If X is an rtable, table, set, or list, the call gammaln(X) computes an elementwise gammaln of X.

$\mathrm{with}\left(\mathrm{MTM}\right)\:$

$M≔⟨⟨7.11732\,7.7921⟩\left|⟨6.8168\,5.4078⟩\right|⟨3.4842\,7.3842⟩|⟨5.0102\,2.6818⟩⟩$

$M≔\left[\begin{array}{cccc}7.11732& 6.8168& 3.4842& 5.0102\\ 7.7921& 5.4078& 7.3842& 2.6818\end{array}\right]$
