基于PCA 和BP 神经网络的人脸识别方法是针对 PCA 方法中存在的高维数问题和它对未训 练过的样本识别率低的缺点而提出的。该方法在预处理的基础上，利用粗糙集对 PCA 降维处理后的人脸特征进行约简，提取其中分类能力强的特征，实现在识别精度不变的情况下，有效的去除冗余信息；然后将约简后的属性输入到神经网络进行规则提取，利用神经网络非线性映射和并行处理的特点，增强对人脸图像识别的泛化能力。实验证明，使用该方法在识别率上有一定的提高(Face recognition method based on PCA and BP Neural Network)

用matlab设计的一个界面，能够自主添加按钮(Matlab interface design, able to independently add button)

matlab实现的线性调频信号的小波变换，可实现信号的时频分析，有很清晰的二维色图(matlab achieve chirp signal wavelet transform, time-frequency signal analysis can be achieved, there is a very clear-dimensional color map)

基于VRML的视景仿真程序，可用于各种姿态下的目标图像生成，对研究图像跟踪非常有用。(VRML based simulation program, which can generate target image with several psoes, which is useful for image tracking.)

说明：  基本的一些matlab源程序分享，欢迎下载，学习。共享(language of matlab important)

这是解调中重要的DDS恢复部分，做成子函数形式，具体的输入输出变量已经表明，请按介绍使用。谢谢站长(This is the most important part, DDS, causing Functions form specific input and output variables have shown, click on the use. Thank you, Captain! !)

换句话说,信号可能仍然是 探测到,但以较低的质量。这是通常所说 对软失败。幸运的是,新的传输的多样性 方案提供了相同软失败。对(one of the receive chains fail, and the other receive chain is operational, then the performance loss is on the order of the diversity gain. In other words, the signal may still be detected, but with inferior quality. This is commonly referred to as soft failure. Fortunately, the new transmit diversity scheme provides the same soft failure. To)

常规波束形成和基于认知的常规波束形成 及其比较(The conventional beamforming and cognitive-based conventional beam formation and)

在secshortest中我希望只得到一条次短路,结果却出来好几条，因此在使用时，要得到次短路，只能用roadcost()函数分别求一下各条路的权重和，找到最小的。(I hope that in secshortest only a short time, the result is out of several, so when used to get at short circuit, can only be used roadcost () function, respectively, for some of the weight of the road and find the smallest.)

用matlab进行视频读取的程序，并附有c语言程序，很有价值。(Using matlab to read the procedures for video, together with c language program, very valuable.)
