actionrwd.segment(..) 🡒 ranvar, process
The function returns a ranvar that represents the probabilistic demand over a specified probabilistic segment. The function
actionrwd.segment() is intended as a support function for
actionrwd.reward() to visualize the demand trajectories internally used by the action reward function.
