The configurable random generator RandGen returns random numbers of a predefined distribution. The user may define the shape of the probability distribution as well as the range of the random numbers. The shape of the probability distribution function is defined by a series of reference points. RandGen is based on the Delphi™ class TRandGen, which is contained in the unit MATH1.

The figure to the right shows the result of 20000 calls to Random with a bimodal distribution defined by 500 reference points. The returned random numbers are indicated by the gray histogram. The blue line shows the underlying probability distribution.
