## Constructor & Destructor Documentation

 chrono::ChDiscreteDistribution::ChDiscreteDistribution ( ChMatrix<> & mx, ChMatrix<> & my )

Create an object that can be used to generate sample numbers according to a discrete probability distribution.

Probability distribution is defined with N discrete values, each with a percentual of probability. The sum of the N probability values must be unit, i.e normalized (but if not, a normalization will be enforced) For example, to get '12.3' for 30% of the times you call GetRandom(), and '150' for the remaining 70% of the times, create ChDiscreteDistribution with mx = [12.3; 150] and my = [0.3; 0.7]
