GAMMALN Log Gamma Function
Section: Mathematical Functions
Usage
Computes the natural log of the gamma function for real arguments. Thegammaln
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
.
Example
Here is a plot of thegammaln
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.
