RandomBeta Routine

Summary

Beta distribution random generator.

Declaration

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

Description

This routine generates Result.Length pseudo random numbers, using the beta 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 beta distribution with parameters a=2.5 and b=3.<>p
