### Usage

```c
#include "stdlib/stats/base/dists/chisquare/mgf.h"
```

#### stdlib_base_dists_chisquare_mgf( t, k )

Evaluates the moment-generating function (MGF) for a chi-squared distribution with degrees of freedom `k` at a value `t`.

```c
double out = stdlib_base_dists_chisquare_mgf( 0.4, 2.0 );
// returns ~5.0
```

The function accepts the following arguments:

- **t**: `[in] double` input value.
- **k**: `[in] double` degrees of freedom (must be non-negative).

```c
double stdlib_base_dists_chisquare_mgf( const double t, const double k );
```

static double random_uniform( const double min, const double max ) {
double v = (double)rand() / ( (double)RAND_MAX + 1.0 );
