gammaln
function takes only a single argument
y = gammaln(x)
where x is either a float or double array. The output
vector y is the same size (and type) as x.
gammaln function over the range [-5,5].
--> x = linspace(0,10);
--> y = gammaln(x);
--> plot(x,y); xlabel('x'); ylabel('gammaln(x)');
which results in the following plot.
