lsb算法将水印图像按最不重要位(LSB)方法嵌入到载体图像中，在把水印从载体图像中提取出来(This is a LSB algorithm that embedding watermark into the least important part of the primary image, and the watermark can be extracted from the primary image.)

说明：  灰色控制 灰色控制 matlab(Control gray gray control matlab)

说明：  对每个对象进行边界提取后标记内部元素,并计算该对象的面积。(The boundary of each object within the elements extracted marker and calculate the area of ??the object.)

说明：  用四阶古典RK方法解初值问题： 取h=1/8。每隔8步打印出数值解与真解的值（u(t)=(t^2)/2-t），画出它们的大致图像，并对产生的结果做出解释。 (with four bands classical RK method for initial value problems : from h = 1/8. Every eight-step numerical solution print and in the true value (u (t) = (t ^ 2)/2-t), they generally draw the images, as well as the results of an explanation.)

Matlab教案，通过理论和实际相结合的方式，详细介绍了matlab的编程方法(This file mainly focuses on the Matlab program design, which gives the theory and the example in the applications.)

永磁电机矢量控制matlab仿真，适合电驱动研究者(Matlab simulation of permanent magnet motor vector control for electrically driven researcher)

matlab EMD 降噪方法 m文件 可以分析振动信号(Analysis of vibration signal can be matlab EMD noise reduction method for M documents)

该算法详细仿真了EKF、UKF以及PF三种方法，进行了对比，只需简单的调整参数就可以观察在不同条件下的滤波效果。(The algorithm detailed simulation of the EKF, UKF and PF three methods were compared, a simple adjustment of parameters can be observed under different conditions of the filtering effect.)

This helps for writing Particle swarm optimization code
