基于一个字嵌入水印0和1bit,原理是将图像转换到空间域后选择系数类嵌入水印，能抗打印扫描攻击(based on a word and embedding watermark 0 1bit, the principle is to convert the image into the spatial domain selection class watermarked coefficient, )

非线性回归通用程序,稍加修改即可用于各种非线性回归(General non-linear regression procedures, a little modification can be used for various non-linear regression)

说明：  永磁同步电机三环矢量控制，有速度环等，经测试正确(Permanent magnet synchronous motor vector control of three-ring, ring, such as speed, were the correct)

利用相关的瞬时值通过在工作过程中的逐步调整参数逼近信号的统计特性，实现最优滤波。由此，我们得到一种最常用的算法——最小均方算法，简称LMS算法。(By using the instantaneous value of the correlation operation of the progressive approximation of the statistical properties of the signal to adjust the parameters to achieve optimal filtering. Thus, we get one of the most commonly used algorithms- the minimum mean square algorithm, called LMS algorithm.)

二分法的Matlab程序实现。求解非线性方程f(x)=0的问题。而方程f(x)是多项式或超越函数又分为代数方程或超越方程。(Dichotomy Matlab program. Solving nonlinear equations f (x) = 0 problems. The equation f (x) is a polynomial or a transcendental function is divided into algebraic equations or transcendental equation.)

层次分析（AHP）/网络分析（ANP)Analytic Hierarchy Process是一种十分实用的决策方法。 是对一些较为复杂、较为模糊的问题作出决策的简易方法，它特别适用于那些难于完全定量分析的问题 num:包括目标层和方案层的总层数 g:行向量（各层准则数量，包括目标层（第一层）和方案层（最后一层））。 w：返回值w是最后决策的方案层的权重，根据输出选择最佳方案 在输入矩阵时请加‘[]’号，否则会出现语法错误。 调运方式：w=hierarchy(num,g)( Analytical Hierarchy (AHP)/Network Analysis (ANP) Analytic Hierarchy Process is a very practical approach to decision making. Is the easy way of making some of the more complex, more ambiguous issues make it particularly difficult for those who complete quantitative analysis of the problem num: The total number of layers including the target layer and the solution layer g: row vector (layers Guidelines number, including the target layer (first layer) and program level (the last level)). W: w The return value is the right solution layer of the final decision of the heavy, choose the best option based on the output when the input matrix please add ' []' No, there would be a syntax error. Transporting way: w = hierarchy (num, g))

惯性导航解算，得出飞行器的经度纬度高度，陀螺仪和加速度计的值(Inertial Navigation Solution, the longitude, latitude, altitude, gyroscope and accelerometer of the aircraft are obtained.)

说明：  UWB optimize and time sync.

Knowledge of the process noise covariance matrix is essential for the application of Kalman filtering. However, it is usually a difficult task to obtain an explicit expression of for large time varying systems. This paper looks at an adaptive Kalman filter method for dynamic harmonic state estimation and harmonic injection tracking.(Knowledge of the process noise covariance matrix is essential for the application of Kalm an filtering. However, it is usually a difficult task to obtain an expli cit for large expression of time varying system s. This paper looks at an adaptive Kalman filter method for dynamic estimation a harmonic state nd harmonic injection tracking.)
