PCA

用于计算李雅普诺夫指数的混沌方程并且实现(Used to calculate the Lyapunov exponents of chaotic equation and achieve)

用matlab编程求解图论中独立集问题(ISP),程序简单明了,希望大家能提出更进一步的改进意见.(Matlab programming using graph theory for solving Independent Set Problem (ISP), the procedure is simple and hope that we can introduce a further improvement.)

此代码是基于DCT的数字水印MATLAB编程，包括水印的置乱和反置乱，嵌入以及提取水印四个部分(This code is based on digital watermark DCT MATLAB programming, including the watermark scrambling scrambling and anti-, four-part watermark embedding and extraction)

本段程序主要实现了函数积分在matlab中的具体操作流程代码。(Functions in integrand )

数字水印源码，基于matlab的，可实现，共同分享。(Digital watermarking source code, based on the matlab can be realized.)

卡尔曼滤波在MATLAB上的实现，本例子是常数型卡尔曼(Kalman filter implemented in MATLAB, and this example is the constant Kalman)

说明：  求取复杂网络图中各个节点的度和度的分布曲线(To calculate the complex degree of each node in network diagram and degree distribution curve )

为感谢惠俊英老师的谆谆教诲，特为好奇诸君奉上水声物理--海洋传播声场模拟的一份武林秘籍！ 当好奇诸君阅毕此卷，再对照轻松跑完六份作业（六路招式），即入“水声物理”之江湖！ BELLHOP与AcousticsToolbox遵照GNU公共许可证进行分发。感谢Michael B. Porter对BELLHOP的原创，也感谢Orlando Camargo Rodríguez此份大道至简的入门秘籍。更感谢由Free Software凝聚起来的自由科学家社区。(Bellhop is a highly efficient ray tracing program, written in Fortran by Michael Porter as part of the Acoustic Toolbox (available at the website of the Ocean Acoustic Library). Bellhop is designed in order to perform two-dimensional acoustic ray tracing for a given sound speed profile c(z) or a given sound speed field c(r; z), in ocean waveguides with flat or variable absorbing boundaries. Output options include ray coordinates, travel time, amplitude, eigenrays, acoustic pressure or transmission loss (either coherent, incoherent or semi-coherent).)

说明：  VMD代码，该程序对信号进行经验模式分解，可以用于故障信号处理，还可以与很对方法结合。如，排列熵，emd,vmd,等，包含VMD、EMD、EEMD工具箱，可用于变分模态分解、EMD以及EEMD谐波检测对对比分析(VMD code, the program for empirical mode decomposition of signals, can be used for fault signal processing, can also be combined with a very good method. For example, permutation entropy, EMD, VMD, etc., including VMD, EMD, EEMD toolbox, can be used for comparative analysis of variational mode decomposition, EMD and EEMD harmonic detection pairs)
