Member Function Documentation

getRand_normalDist()

template<typename RealType = double>

double NAV::RandomNumberGenerator::getRand_normalDist ( RealType mean = 0.0, RealType stddev = 1.0 )

inline

Gets a random number from a normal distribution.

Template Parameters

RealType

The result type generated by the generator. The effect is undefined if this is not one of float, double, or long double

Parameters

mean	The μ distribution parameter (mean)
stddev	The σ distribution parameter (standard deviation)

Returns

Random number

getRand_uniformIntDist()

template<typename IntType = int>

double NAV::RandomNumberGenerator::getRand_uniformIntDist ( IntType min = 0, IntType max = std::numeric_limits<IntType>::max() )

inline

Gets a random integer number from an uniform distribution.

Template Parameters

IntType

The result type generated by the generator. The effect is undefined if this is not one of short, int, long, long long, unsigned short, unsigned int, unsigned long, or unsigned long long.

Parameters

min	Minimum value
max	Maximum value

Returns

Random number

getRand_uniformRealDist()

template<typename RealType = double>

double NAV::RandomNumberGenerator::getRand_uniformRealDist ( RealType min = 0.0, RealType max = 1.0 )

inline

Gets a random real number from an uniform distribution.

Template Parameters

RealType

The result type generated by the generator. The effect is undefined if this is not one of float, double, or long double

Parameters

min	Minimum value
max	Maximum value

Returns

Random number

resetSeed()

void NAV::RandomNumberGenerator::resetSeed ( size_t id = 0 )

inline

Reset the seed to the internal seed or the system time.

Parameters

id	Some id used to make a unique hash when using the system time to set the seed

resetSeedOnce()

void NAV::RandomNumberGenerator::resetSeedOnce ( uint64_t userSeed )

inline

Reset the seed to the specified seed, but do not update the internal seed.

Parameters

[in]

userSeed

Seed to use once
