3.5.3.2.6 Gampdf

Definition

Y = gampdf(X,a,b) computes the gamma probability density function at each of the values in X using the corresponding shape parameters in a and scale parameters in b.

$f(x|a,b)=\frac 1{b^a\Gamma (a)}x^{a-1}e^{\frac{-x}b}$

Parameters

x (input, double): $x > 0$
a (input, double): shape parameter $a >0$ .
b (input, double): scale parameter $b >0$ .
