wavelift

matlab6.5辅助小波与应用，一本很好的小波学习书。(matlab6.5 secondary wavelet and application of wavelets to study a good book.)

k-d树的matlab程序，包含了KDTREE, KDTREEIDX and KDRANGEQUERY functions。提供了两个Demo scripts(kdtree_demo.m & kdrange_demo.m),很实用( This distribution contains the KDTREE, KDTREEIDX and KDRANGEQUERY functions. Included are the source code files in kdtree/src, as well as precompiled mex files for the following systems: - Mac OS X (Matlab 6.5) - Redhat Linux (Matlab 6.5) - Windows (Matlab 6.1) Two demo scripts are provided (kdtree_demo.m & kdrange_demo.m). The new features added June 2004: + You can now use N dimensional data points, where N>3. + Use KDTREEIND to return the index value to the closest point, instead of the closest point values. + KDRANGEQUERY can now return these index values as well.

一个老外编写的DE算法代码，执行效率搞，代码速度快(A foreigner prepared by the DE algorithm code execution efficiency engage in code faster)

Pattern Recognition file to read the letter or the numbers so we can recognize it

SPWD - smoothed Pseudo Wigner-Ville Distribuition

for signal analysis and estimation methodes

用matlab编写，实现对一幅图像进行线性灰度变换。(Prepared using matlab, achieve a linear gray transform the image.)

说明：  迫零预编码是基于单小区，简单且实用的信道检测算法，用于和MMSE多小区用户的信道检测比较(Zero-forcing precoding is based on a single-cell, channel detection is relatively simple and practical channel detection algorithm for multi-cell users and MMSE)

ADRC的主程序。包括跟踪微分器，扩张状态观测器以及非线性反馈环节的程序(ADRC main program. A program for tracking a differential device, an extended state observer and a nonlinear feedback link)

预测程序，可以预测各种时间系列的数据：如股票、地震，降水，水文等等。(emd programmer)
