Description

`param_type` public construct/copy/destruct

```
( k = ,  lambda = );
```
Constructs the parameters of a non_central_chi_squared_distribution. k and lambda are the parameter of the distribution.

Requires: k > 0 && lambda > 0

`param_type` public member functions

```
 () ;
```
Returns the k parameter of the distribution
```
 () ;
```
Returns the lambda parameter of the distribution

`param_type` friend functions

template<typename CharT, typename Traits> 
   
  ( os, 
              param);

Writes the parameters of the distribution to a std::ostream.

template<typename CharT, typename Traits> 
   
  ( is, 
              param);

Reads the parameters of the distribution from a std::istream.

```
 ( lhs,  rhs);
```
Returns true if the parameters have the same values.
```
 ( lhs,  rhs);
```
Returns true if the parameters have different values.
