典型的正交匹配追踪OMP算法的matlab源程序，结构合理，简单易懂(Typical orthogonal matching pursuit OMP algorithm matlab source, reasonable structure, easy to understand)

一个简单的ezw编解码程序,希望对大家有所帮助。(one simple code about encoding and decoding。I hope it makes any help。)

利用CC方法可同时求时延与嵌入窗大小。程序中给的是Lorenz的例子。可以修改输入数据。(CC method can be used at the same time seeking delay and embedding window size. Program to the Lorenz case in point. Can modify the input data.)

说明：  平均周期图法和平滑平均周期图法估计功率谱 从经典功率谱估计周期图法原理入手，从理论上分析了其存在的局限性，借助Welch算法对其进行修正。依靠Matlab强大的数值分析和信号处理能力进行实验!! 用周期图法和welch法分别估计了一下信号的功率谱密度。采样频率200Hz，时间序列长度2048，FFT数据点数2048。其中welch法使用hanning窗，窗口长度600．(Average periodogram and periodogram smoothing method to estimate the average power spectrum from the classical power spectrum estimation periodogram principle starting from the theoretical analysis of the limitations of its existence, with the Welch algorithm, amending them. Rely on the powerful Matlab numerical analysis and signal processing capabilities to experiment!! With periodogram and welch method were estimated signal power spectral density about. Sampling frequency of 200Hz, the time sequence length 2048, FFT data points 2048. Welch method which uses hanning window, the window length of 600.)

Orthogonal Least Squares Estimate on a plane, in the simple case of a linear equation, is in fact a problem that can be easily solved analytically with no approximation (see pdf file for detailed explanation). Notice that in the general multidimensional case, an analytical solution may not exist (although Mr. Carr s function is an efficient approximation of the solution).

zemax与matlab调用程序，当您用matlab分析复杂数据时，可以利用zemax光路计算工具提供原始数据，由matlab分析，并且可以驱动zemax优化，对自由曲面的优化更为重要，此代码为matlab调用zemax的函数库。(ZEMAX and Matlab : A Powerful Pair ZEMAX features a built-in DDE (Dynamic Data Exchange) server that allows other Windows® applications access to ZEMAX functions. Programming DDE applications can be somewhat complex if you are working in a compiled language such as C++. An alternative is to use one of the scripting languages such as Tcl, Python or Matlab. Matlab is a great choice since it is much more than a scripting language. Matlab provides a wealth of functions for processing and visualizing scientific and engineering data and there are toolboxes for Matlab that extend the basic capabilities into a wide variety of more specialized areas and disciplines. )
