NormalRandomFunctor (Engine const &generator=Engine::global()) | |
NormalRandomFunctor (double mean, double stddev, Engine &generator=Engine::global()) | |
double | operator() () const |
Functor to create normal variate random numbers.
This functor encapsulates the function normal()
of the given random number Engine
(usually RandomTT800
or RandomMT19937
) in an STL-compatible interface.
Traits defined:
FunctorTraits<UniformIntRandomFunctor<Engine> >::isInitializer
is true (VigraTrueType
).
NormalRandomFunctor | ( | Engine const & | generator = Engine::global() | ) |
Create functor for standard normal random numbers using the given engine.
That is, mean is 0.0 and standard deviation is 1.0.
NormalRandomFunctor | ( | double | mean, |
double | stddev, | ||
Engine & | generator = Engine::global() |
||
) |
Create functor for normal random numbers with given mean and standard deviation using the given engine.
double operator() | ( | ) | const |
Return a random number as specified in the constructor.
