this simulation is a way for watermarking and steganography with WOW

maze solution. it is a solution for maze problem with matlab code. in this solution I used very simple functions and it is easy for everyone.

电缆的EMC设计分析介绍，具体介绍了场在导线中感应的噪声以及电缆之间的串扰(EMC introduces the design of the cable analysis)

进行多项式拟合曲线和参数，给出数据和m文件(Polynomial curve fitting and parameters, given the data and m files)

解非线性方程 能过解复根 实根 但需要逼近(help you save equation conclude different answer)

自然梯度法盲信源分离，固定步长，可手动输入步长，样本个数及仿真次数(Source separation of natural gradient literacy, fixed step, you can manually enter the step size, sample size and simulation times)

其实操作系统在调用 main 函数时是传参数的，main 函数最标准的形式应该是 int main(int argc, char *argv[])，在第 6 节 “指向指针的指针与指针数组” 详细介绍。C 标准也允许 int main(void)这种写法，如果不使用系统传进来的两 个参数也可以写成这种形式。但除了这两种形式之外，定义 main 函数的其它写法都 是错误的或不可移植的。(The 88-bytes (704-bits) in the Configuration zone contain manufacturing identification data, general device, and system configuration, and access restriction control values for the slots within the Data zone. The values of these bytes can always be obtained using the Read command. The bytes of this zone are arranged as shown in Table 2-2)

kalman滤波程序，Matlab编写的程序(kalman filtering procedures, Matlab preparation procedures)

在matlab环境下，用于评估算法好坏，检索性能优劣等(In the matlab environment, good or bad for the evaluation algorithm, retrieval performance advantages and disadvantages, etc.)

无约束问题最优化方法的核心问题是选择搜索方向。 以正定二次函数为例，来观察两个方向关于矩阵Ａ共轭的几何意义(Unconstrained optimization problems are most core issue is to choose the search direction. In definite quadratic function, for example, to observe both directions on the matrix A conjugate geometric meaning)
