reduction of a symmetric matrix to symmetric tridiagonal form

DES function for the encryption of DES,use matlab to make it possible,first input in the function is plaintext ,second one is key,and last is to choose encrypt or decrypt

利用matlab自带的BP神经网络工具箱对duffing混沌背景模型进行相空间重构与预测，程序中已经给出duffing函数，主函数中也给出了主要注释，方便大家学习交流。(BP' s own use matlab neural network toolbox for duffing chaotic background model and prediction of phase space reconstruction, the program has been given duffing function, the main function also gives the main note, we facilitate learning exchanges.)

MOEAD算法实现，含测试函数，有较为详细的注释。（MATLAB平台实现）(MOEAD algorithm implementation.)

并行和串行级联码已成为一种实用的方法，取得了良好的性能。在此论文中，我们将介绍并行和串行级联单奇偶校验乘积码。我们对这种码的码重分布进行了分析，其性能是有界的。仿真的结果确定了在高信噪比情况下的性能界限。这种码（与一些变种）的性能证明对于降低译码复杂性和适当的短码长具有相当良好的效果。(Parallel and serial concatenated code has become a practical way to obtain good performance. In this paper, we will introduce the parallel and serial concatenated single parity check product codes. We re-distribution of this code code analysis, and its performance is bounded. The results of the simulation to determine the performance limits in the case of a high signal-to-noise ratio. Proof of performance of this code (with some variants) having a fairly good effect for reducing the decoding complexity and the appropriate short code length.)

可以在蓝色背景下找到肤色散点分布图，从而确定肤色在YCBCR空间内的分布情况(Can be found in the blue background color scatter distribution, to determine the color space in the distribution of YCBCR)

非常好用的MATLAB程序，不下会后悔的(MATLAB is very useful procedure, we will regret over the)

这个源码提供了穿墙雷达反向投影成像算法的实现(backprojection（BP）算法)
