用小波来实现纹理检测的一个MATLAB代码。很有用，简单明了。(using gabor wave to detecte texture)

this codel model rician clutter

说明：  A new technique of free-space simulation has been developed for solving unbounded electromagnetic problems with the finite-difference time-domain method.

说明：  分为三个函数，第一个函数的功能是用于读取ecg信号，找到小波变换模极大序列；第二个函数是子程序，用于多分辨率分解，使用 A trous 算法在分解的过程中，同时给出各级的细节和概貌，它们和原数据有着同样的长度；第三个函数是函数子程序，用于多分辨率分析中的重建。(Divided into three functions, the function of the first function is used to read the ecg signal, find the wavelet transform modulus maxima sequence second function is a subroutine for use in multi-resolution decomposition, the decomposition algorithm using A' trous process, and gives details of all levels and profiles, they are the original data have the same length third function is a function subprogram, for multi-resolution analysis of the reconstruction.)

说明：  遗传算法实现多峰函数优化问题 大家爱看的哦啊大家奥迪啊 安科技大大的安静的(Genetic Algorithms for Multimodal Optimization We all like to watch the oh ah ah An Audi quiet technology greatly)

进行图像配准的matlab程序，可以显示配准后的图像及配准后的融合图像(image registration by matlab)

用M语言编写的画多元数据平行坐标图代码，数据用的是一组蔬菜油（国际期刊）数据，写得不好，多指教。(By M art multi-language data parallel coordinates graph code, data used are a group of vegetable oils (International Journal) data, not well written, multi-index.)

最后的测试程序，得出文本检索的正确率和召回率(In the end, the cosine similarity of texts is used to measure the similarity between the query and documents. The data comparison indicates that this algorithm has well experimental results. Moreover, it gets the advantage over the classic LSA retrieval algorithm in precision and operational efficiency.)
