Energy Decay Curve and Energy Decay Relief

In this section, you will complete the provided Matlab listings for observing the Energy Decay Curve and its generalization, the Energy Decay Relief.

(20 pts) Complete indicated sections in the Matlab files edrAndPLot.m and edcAndPLot.m in order to calculate the Energy Decay Curve (EDC) and Energy Decay Relief (EDR) of a signal. Turn in the new code you wrote, and plot the EDC and EDR for the impulse response of an actual acoustical space and for the impulse responses of the reverberators you built in problems 1 and 2.
