compress sensing aimed at cognitive radio is performed in this file,hope everyone can come up with some suggestions

西北工业大学研究生课程，数字信号处理上机作业三(Northwestern Polytechnical University post-graduate courses, digital signal processing, machine operating)

说明：  请仔细阅读简介！ 此书电子版较大，我分为三个压缩包进行上传，点进我主页下载全部压缩包，再一起解压，一定要下完了一起解压！(Please read the introduction carefully! Pudn has a complete program for this book, but there is no original book. The electronic version of this book is relatively large. I upload it in three compressed packages. Click on my home page to download all the compressed packages, and then decompress them together (the platform limits the file size). We must decompress them together when we are finished!)

一个通过实际应用的“ 人工鱼群算法”，效果很好的。(Through the practical application of the " artificial fish-swarm algorithm," good effects.)

利用matlab实现的BP神经网络算法，对初学者很有用(matlab neural network to achieve the BP algorithm)

用于效率评价的模型，检验成本支出评价的模型(Model, the inspection cost evaluation model for efficiency evaluation)

Warning: AVIREAD will be removed in a future release. Use MMREADER instead.

控制表的程序实现，用语言编写存入文本文档中(Program control table, use the language into the text document)

说明：  code to do something i dont kno tamala

KPCA的基本思想是首先将低维输入空间中各变量之间的非线性关系通过非线性映射映射到高维特征空间中，然后在高维特征空间中进行主元分析，求取数据在非 线性主元上的投影。这一非线性映射的具体形式并不需要求取，是通过适当的内积函数实现的，这种内积函数可以诱导出从原始输入空间到高维特征空间的隐含映射(核 函数)，因此称作核函数主元分析。通过选取不同形式的核函数，就可以处理大量的非线性问题。
