RandomGamma Routine

Summary

Gamma distribution random generator.

Declaration

Procedure RandomGamma(A, B: TSample; Results: TDenseMtxVec; Seed: Integer = -1);

Description

This routine generates Result.Length pseudo random numbers, using the gamma distribution with parameters a and b. The random numbers are stored in the Results vector. An exception is raised if Result vector is complex.

Example 1

Generate 2000 random numbers by using the gamma distribution with parameters Nu1=4 and Nu2=0.25.

    Res.Size(2000);
    RandomGamma(4,0.25, Res);
  end;

    Res->Size(2000,false);
    RandomGamma(4, 0.25, Res, -1);
  }
