DESCRIPTION

CNRandomMix generates random numbers from a mix of several CNRandom distributions.

Constructors:

CNRandomMix();

CNRandomMix(CNParam *param);

CNRandomMix(CNRandomMixEntry *tab, int length, CNRNG *gen);

Initializes a CNRandomMix distribution with a base random number generator gen and a table of several distributions. The following example shows how to use a CNRandomMixEntry table with 3 different distributions and their corresponding probabilities for a CNRandomMix distribution:

CNLogNormal ex1(10, 0.5, &generator1);
CNNormal    ex2(12, 0.3, &generator2);
CNHyperExp  ex3(10, 0.5, &generator3);

CNRandomMixEntry tab[] = {
    { 0.1, &ex1 }, { 0.5, &ex2 }, { 0.4 &ex3 }
};

CNRandomMix ex(tab, 3, &generator);

In addition to the member functions required by CNCL, CNRandomMix provides:

virtual double operator() ();

Draws a random number.
