modelGenerateRandomNumbers
Generate random numbers with the various random number generators
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
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:
