Gampdf
Gampdf-func
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} f(x|a,b)=\frac 1{b^a\Gamma (a)}x^{a-1}e^{\frac{-x}b}](../images/Gampdf_(function)/math-05b0e4b4ecf6e257024f923168d90bae.png)
