Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This example demonstrates how to utilize the random number generators of package Math.Random.Generators in a Modelica model. The example calculates random numbers in the range 0 .. 1 of the available random number generators periodically with a sample period of 0.05 s. Simulations results are shown in the figure below:
