#### stdlib_base_dists_gumbel_median( t, mu, beta )
#### stdlib_base_dists_gumbel_mgf( t, mu, beta )

Evaluates the [moment-generating function][mgf] (MGF) for a [Gumbel][gumbel-distribution] distribution with parameters `mu` (location parameter) and `beta > 0` (scale parameter).


```c
double out = stdlib_base_dists_gumbel_mgf( -1.0, 0.0, 1.0 );
// returns ~6.0
double out = stdlib_base_dists_gumbel_mgf( -1.0, 0.0, 3.0 );
// returns 6.0
```

The function accepts the following arguments:
