Matlab的模拟退火算法工具箱。并附有sample文件夹，有助于初学者进行学习测试。(The Matlab simulated annealing algorithm toolbox. With the sample folder, will help beginners learn the test.)

MATLAB下的GPS_tool 包括最基本的算法和实例(navigation gps in matlab)

Pcnn神经网络筛选特征因子代码，pca预处理代码，特征因子整合代码，等等，都是好东西啊(Pcnn neural network filter characteristic factor code, pca pretreatment code, characteristic factor integration code, etc., are all good things ah)

鉴于网上合成孔径雷达的资料比较少，上传一些老师给的文献资料，希望对大家有帮助(Given the online synthetic aperture radar data is relatively small, upload some literature teacher, I hope to help everyone)

级联MUSIC算法将二维谱峰搜索变为一维谱峰搜索，大大降低算法复杂度。(Cascade MUSIC algorithm to two-dimensional spectrum peak search into a one-dimensional spectrum peak search, greatly reduce the complexity of the algorithm.)

内共有两个程序：1.用Mallat算法实现一维小波变换；2.用DWT实现二维小波变换。 从仿真图可以加深对小波概念及小波变换的原理。(A total of two procedures: 1. Mallat algorithm using one-dimensional wavelet transform 2. With the realization of two-dimensional wavelet transform DWT. From the simulation wavelet map can deepen their understanding of the concept and the principle of wavelet transform.)

说明：  利亚普诺夫指数是混沌预测和混沌的重要参数，代码中给出利亚普诺夫指数和wolf算法(Liapunov index and the wolf chaos algorithm)
