Detailed Description

Example program illustrating use of ns3::EmpiricalRandomVariable.

This example illustrates

• Creating an EmpiricalRandomVariable instance.
• Switching the mode.
• Using the sampling mode
• Switching modes
• Using the interpolating mode

Consult the ns-3 manual for more information about the use of the random number generator
