说明：  利用小波变换实现对故障信号的特征提取 构造特征向量(Wavelet transform feature extraction of fault signals structural feature vector)

对信号进行短时傅里叶变换的程序，可以通过调用改程序分析信号的时频分布(this code is used to analysis the short time fourier transform of the signal )

实现对信号的连续、离散小波分解，程序简单易读(Achieve continuous signal, discrete wavelet decomposition, the program simply read)

遗传算法优化下的神经网络模型，可以用于径流预测(ga ann)

使用lingo求旅游商问题。 当然，如果数据量大的话，还是用经典算法吧。(Tourism operators seek to use lingo problem. Of course, if the data is large, then it is the classical algorithm used.)

DTW-语音识别，是在matlab中做的，比较方便快捷了。(DTW-speech recognition, in matlab to do, the more convenient of the.)

we propose and demonstrate a method for increasing the resolution of a limited aperture and limited pixel size of the detector in an optical system by illuminating the input with a speckle pattern. This method includes an encoding function that encodes the high spatial frequencies of the object that can not pass the resolving limitations. Afterwards we use a decoding pattern which is the same pattern of the applied encoding function.

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.
