灰色系统GM（1，1）模型的源代码，实现在数据不充分的情况下对未来的预测。(Gray system GM (1,1) model of the source code, data is not sufficient to achieve in the case of predictions for the future.)

拟合 matlab!拟合 matlab!拟合 matlab!拟合 matlab!(matlab nihequxian.matlab nihequxian.matlab nihequxian.)

This document is intended to serve as an introduction to Wavelet processing through a set of Matlab experiments. These experiments will gives an overview of three fundamental tasks in signal and image processing : signal, denoising and compression. These scripts are selfs contents (needed additional Matlab functions can be downloaded while reading the lectures). Each one of these five lectures should take between 1h and 2h in order to tests the various features of the scripts. One should copy/paste the provided code into a file names e.g. tp1.m, and launch the script directly from Matlab comand line > tp1 . Some of the scripts contains "holes" that you should try to fill on your own. I also provide the complete correction of these lectures as a set of Matlab scripts, but you should try as much as possible to avoid using them.

说明：  matlab 程序 是自己写的，太简单科别笑我 希望有人支持(matlab program is written in their own, too simple divisions laugh, I hope there is support for)
