本实验要求开发一个基本的哈尔小波变换程序包，用于后续的实验。实验中使用哈尔基函数特有的“平均”与“差分”方法。首先要编写一个计算哈尔小波的j-尺度离散小波变换程序。并且要编写一个计算哈尔小波的j-尺度的逆离散小波程序，并用课本上的例7.8来验证所编写的程序-The experiment calls for the development of a basic package Haar wavelet transform for the follow-up experiment. Harki function used in the experiment-specific " average"　and " difference"　method. First of all, to be prepared a calculation of the Haar wavelet j-scale discrete wavelet transform procedures. And to prepare a calculation of the Haar wavelet scale j-inverse discrete wavelet procedures, and the cases of books to verify the preparation of 7.8 procedures
