多种子点的区域增长，程序可在matlab环境中更直接运行；(Many seeds of regional growth, the program can be more direct in matlab environment to run )

这次是对添加水印的图像中添加一种高斯噪声的matlab程序(The watermark image is added to add a Gaussian noise process)

说明：  可以教你快速入门的MATLAB教程，个人觉得很好，值得学习一下(not bad)

使用matlab实现最小二乘算法，计算测量的待定点的精度(Using matlab to achieve least-squares algorithm to calculate the accuracy of measurement points to be determined)

FM信号的调制解调的simulink仿真，亲自测试已经通过，大家可以放心下载使用。(FM signal modulation and demodulation simulink simulation, personally test has passed, you can be assured to download.)

这是龚纯《精通MATLAB最优化计算》随书源码(M文件)。基于MATLAB优化工具箱，代码包含的内容有：牛顿法等无约束一维极值问题、单纯形搜索法等无约束多维极值问题、Rosen梯度投影法等约束优化问题、L-M法等非线性最小二乘优化问题、线性规划、整数规划、二次规划、粒子群优化、遗传算法。(This is pure Gong " Mastering MATLAB optimization calculations," with the book source (M file). Based on MATLAB Optimization Toolbox, the content code contains: Newton and other non-binding one-dimensional extremum problems, such as simplex search method for unconstrained multi-dimensional extremum problems, Rosen gradient projection method and other constrained optimization problems, LM non-linear law least squares optimization problem, linear programming, integer programming, quadratic programming, particle swarm optimization, genetic algorithm.)

采用MATLAB语言编写的应用实例，主要目的是了解MATLAB的功能，实现对M语言的熟练掌握。(MATLAB language using an application example, the main purpose is to understand the function of MATLAB to achieve proficiency on the M language.)

ACF中包含两个m文件，一个是自协方差函数（可单独使用）。另一个是自相关函数计算，其调用autocov函数。(ACF contains two m files, one is self-covariance function (which can be used alone). The other is calculated from the correlation function, which calls autocov function.)

速率方程求解，的详细过程。还有范例,方便一步一步学习(Rate equations, the detailed process. There sample rate equations, the detailed process. There are examples)

说明：  这是一个matlab小程序,可用于求解微分方程,特别是抛物型的微分方程(Matlab This is a small program that can be used to solve differential equations, in particular the type of parabolic differential equations)
