Statistics: gamstat

### Function Reference: `gamstat`

statistics: [m, v] = gamstat (k, theta)

Compute statistics of the Gamma distribution.

`[m, v] = gamstat (k, theta)` returns the mean and variance of the Gamma distribution with with shape parameter k and scale parameter theta.

The size of m (mean) and v (variance) is the common size of the input arguments. A scalar input functions as a constant matrix of the same size as the other inputs.

There are two equivalent parameterizations in common use:

1. With a shape parameter k and a scale parameter θ, which is used by `gamrnd`.
2. With a shape parameter α = k and an inverse scale parameter β = 1 / θ, called a rate parameter.
