Class template uniform_real_distribution

Class template uniform_real_distribution

boost::compute::uniform_real_distribution — Produces uniformily distributed random floating-point numbers.

Synopsis

// In header: <boost/compute/random/uniform_real_distribution.hpp>

template<typename RealType = float> 
class uniform_real_distribution {
public:
  // types
  typedef RealType result_type;

  // construct/copy/destruct
  uniform_real_distribution(RealType = 0.f, RealType = 1.f);
  ~uniform_real_distribution();

  // public member functions
  result_type a() const;
  result_type b() const;
  template<typename OutputIterator, typename Generator> 
    void generate(OutputIterator, OutputIterator, Generator &, 
                  command_queue &);
};

Description

The following example shows how to setup a uniform real distribution to produce random float values between 1 and 100.

// initialize the default random engine
boost::compute::default_random_engine engine(queue);

// setup the uniform distribution to produce floats between 1 and 100
boost::compute::uniform_real_distribution<float> distribution(1.0f, 100.0f);

// generate the random values and store them to 'vec'
distribution.generate(vec.begin(), vec.end(), engine, queue);

`uniform_real_distribution` public construct/copy/destruct

```
uniform_real_distribution(RealType a = 0.f, RealType b = 1.f);
```
Creates a new uniform distribution producing numbers in the range [a, b).
```
~uniform_real_distribution();
```
Destroys the uniform_real_distribution object.

`uniform_real_distribution` public member functions

```
result_type a() const;
```
Returns the minimum value of the distribution.
```
result_type b() const;
```
Returns the maximum value of the distribution.

template<typename OutputIterator, typename Generator> 
  void generate(OutputIterator first, OutputIterator last, 
                Generator & generator, command_queue & queue);

Generates uniformily distributed floating-point numbers and stores them to the range [first, last).
