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 \(b >0\).
