应用四步相移法实现包裹相位的解缠，另有解缠结果(Application of four step phase shifting method to achieve the wrapped phase unwrapping, otherwise the unwrapping results)

基于马尔科夫链概念，3状态概率转移矩的matlab实现(Based on the concept of Markov chain, the realization of the 3 stats matrix s transfer probability matrix in matlab)

turbo码编解码，可用于3G LTE链路仿真，我用在2010年中兴程序设计大赛的，绝对可用(turbo encoding and decoding, can be used for 3G LTE link simulation, I use ZTE 2010 Programming Contest, absolutely free)

用基于 Matlab 的小容量 FFT (比如 256×256)程序，将取样窗口划分为 若干个全等的小矩形,对每个小矩形内离散点的复振幅作 FFT 变换,然后将所有变 换结果叠加，再乘以复数相位因子,相当于对整个物面上点进行菲涅耳衍射计算， 利用这种方法可以迅速的实现高精度的轴对称傍轴光学系统中的激光衍射计算 (With a small volume based on Matlab FFT (eg 256 × 256) procedure to sample window divided into a number of small identical rectangles, each small rectangle of discrete points within the complex amplitude for the FFT transform, and then transform the results of all the superposition multiplied by the complex phase factor, the equivalent point on the object plane Fresnel diffraction calculation, the use of this method can rapidly achieve high-precision optical system axis of symmetry in the paraxial calculation of laser diffraction)

该代码能使你很方便地运用matlab软件进行灰色预测。(The code allows you to easily use gray prediction matlab software.)

learning programming with Matlab

它是基于matlab的端点检测程序的代码，相信对大家有用。(It is based on the endpoint detection matlab program code, I believe all of us.)

音频系统，coding, modulation, AWGN, 通过最小距离探测码元，解码，播放。根据不同的SNR，测试在多小的SNR情况下，人耳能识别音频。(Audio systems, coding, modulation, AWGN, by minimizing the distance detection symbol, decoding, playing. Depending on the SNR, the test in the case of multiple small SNR, the human ear can identify audio.)

说明：  浅谈加权最小二乘法及其残差图及其详细的讨论(On the weighted least squares method and the residual map and detailed discussions)

memetic是一种高效的文化进化计算方法，该范例以Rosenbroek函数为例进行了演示，你也可以加入其它函数进行测试。(memetic cultural evolution is an efficient method of calculating the sample to Rosenbroek function as an example of the presentation, you can also add other functions to be tested.)
