Member Function Documentation

float TRandomNormal::Random (  const float &  middle, const float &  variance )

Generate random number in range (-infinity,infinity) with normal (Gaussian) distribution. For generating is used Box-Muller transformation from uniform distribution. Distribution has parametres (middle, variance). Parameters: middle  [in] middle of Gaussian distribution variance  [in] variance of Gaussian distribution (should be positive) Definition at line 122 of file Random.cpp. References DBGASSERT, and Random(). Here is the call graph for this function:

float TRandomNormal::Random (  void   )

Generate random number in range (-infinity,infinity) with normal (Gaussian) distribution. For generating is used Box-Muller transformation from uniform distribution. Distribution has parameters (middle = 0, variance = 1). Definition at line 104 of file Random.cpp. References NSMath::NSStdMath::cos(), NSMath::NSStdMath::log(), NSRoutines::PI, NSRandom::TRandom::Random(), and NSMath::NSStdMath::sqrt().
