说明：  率失真函数是在给定信源和失真度量情况下，求满足保真度准则的平均信息率的极小值。本程序给出了两种特殊情况下的率失真函数的计算(Rate-distortion function is a given source and distortion measure case, seeking to meet the fidelity criteria, the average information rate of the minimum. This procedure presents two special circumstances, the calculation of rate-distortion function)
