StatRandom.RandomPoisson Function

Poisson distribution random generator.

Pascal
procedure RandomPoisson(const lambda: double; const Results: TMtxVecInt; Seed: Integer = -1);

This routine generates Result.Length pseudo random numbers, using the Poisson distribution with parameter lambda. The random numbers are stored in the Results vector. An exception is raised if Result vector is complex.

Generate 2000 random numbers by using the Poisson distribution with parameter lambda=2.31.

Uses MtxExprInt, StatRandom;
procedure Example;
  var Res: VectorInt;
begin
  Res.Size(2000);
  RandomPoisson(2.31, Res);
end;
#include "MtxExprInt.hpp"
#include "StatRandom.hpp"
void __fastcall Example()
{
  VectorInt Res;
  Res.Size(2000,);
  RandomPoisson(2.31, Res,-1);
}
