中文说明：在本例终，用x(i)来表示抽样值，y(i)来表示将抽样值x(i)进行对数压缩后的值，这样x(i)对应分层电平值和量化电平值，而y(i)对应分层电平值编号和量化电平值编号。是利用13折线法得到的量化编码的matlab程序。
English Description：
At the end of this example, X (I) is used to represent the sampling value, and Y (I) is used to represent the value after logarithmically compressing the sampling value x (I), so that x (I) corresponds to the layered level value and the quantized level value, and Y (I) corresponds to the layered level value number and the quantized level value number. Is the use of 13 broken line method to get the quantization coding matlab program.
