这个工具箱是对水平集方法的matlab程序的搜集。这些程序应用数值算法在任一维度来近似基于时间变化的汉密尔顿雅可比偏微分方程的解。汉密尔顿雅可比偏微分方程常用动画演示动态隐式曲面，计算流体动力学，并且它是独立在最优控制，微分博弈机器人，金融数学，连续的可达性等兴趣领域。(The Toolbox of Level Set Methods (ToolboxLS) is a collection of Matlab routines that implement numerical algorithms to approximate the solution of the time-dependent Hamilton-Jacobi (HJ) partial differential equation (PDE) in any number of dimensions. The HJ PDE is often used for simulating dynamic implicit surfaces in animation and computational fluid dynamics (CFD), and it is of independent interest in areas of optimal control, differential games, robotics, financial mathematics, continuous reachability, etc.)

说明：  粒子群算法求函数最优解粒子群算法求最优解。(Particle Swarm Optimization)

数字水印图像的攻击测试 包括滤波、剪切、添加噪声、jepg压缩攻击等等(Attack test digital watermarking images, including filtering, cropping, adding noise, jepg compression attack, etc.)

本书重点介绍matlab在数字信号处理中的基本应用及编程方法。(this book mainly introduce the basic application of MATLAB in DSP field)

包括：1、关于STBC技术在频率选择性信道下的性能分析程序 2、对STBC性能的改进系统：STBC-OFDM系统的性能分析程序(掳 眉脌 篓 拢 潞 1 隆 垄 鹿 脴脫脷STBC 录 录 脢玫脭脷脝渭脗脢脩 隆 脭帽脨脭脨脜渭脌脧脗渭脛脨脭脛脺 脰脦枚 鲁 脤脨貌2 隆 垄 露 脭STBC脨脭脛脺渭脛 赂 脛 陆 酶脧渭脥 鲁 拢 潞 STBC-OFDM脧渭脥 鲁 渭脛脨脭脛脺 脰脦枚 鲁 脤脨貌)

地震数据处理方面matlab代码，能够地震数据进行简单处理和绘图(Seismic data processing matlab code, simple to seismic data processing and graphics)

用MatLab编的锁相环,希望对大家有帮助(Series of phase-locked loop with MatLab, we want to help)
