说明：  面阵波束形成，由两条垂直线阵组成的面阵波束接收天线(Planar array beam forming, by the vertical line array consisting of two side beam receiving antenna array)

matlab实现商标文字分割~第一部分计算列梯度差，计算每个像素的列方向一定范围内（n）最大值和最小值的差距,统计该差值超过某一设定域值T的像素的个数，并将该统计个数存在 GY 向量。，第二部分计算行梯度差，计算每个像素的行方向一定范围内（n）最大值和最小值的差距，统计该差值超过某一设定域值T的像素的个数，并存在 GX 向量(matlab text segmentation ~ realize trademarks calculations are shown in the first part of the gradient difference, calculated for each pixel column direction of a certain range (n) the difference between maximum and minimum values, statistics of the difference exceeds a certain threshold T set of pixels of a few, and the statistics of the number of vectors exist GY. , The second part of the calculation line gradient difference, calculated for each pixel within a certain range direction (n) the difference between maximum and minimum values, statistics of the difference exceeds a certain threshold T set the number of pixels, and the existence of GX Vector)

说明：  此程序中将两个离散时间信号卷积，在数字信号处理过程中很有用！(conversion)

在matalab开发环境下的实现时域信号多尺度的分析，可用于信号的特征抽取和故障诊断(Multi-scale analysis of time-domain signal achieved in matalab development environment can be used for feature extraction and fault diagnosis signal)

基于matalab simulink的整流器的双闭环仿真 (Dual closed-loop simulation based rectifier matalab simulink)

对图像求拉普拉斯变换，分别使用中心为-4、-8其他值均为1的拉普拉斯滤波器(Laplace transform of image, Laplace filter respectively using the center for- 4、-8，other value for 1)

经典粒子群算法的matlab实现。用函数进行测试实验，并给出算法寻优迭代的效果图(Classical PSO algorithm matlab. Experiments with test functions, and gives an iterative optimization algorithm renderings)

说明：  二维的悬臂梁问题，简单实用，采用EFGM方法，适合初学者。(2-dimensional cantilever beam problem, simple and practical, using EFGM method, suitable for beginners.)

用3中误差扩散滤波器实现误差扩散，分别是floyd stein, sierra, Stenenson滤波器(Error diffusion filter with a 3 to achieve error diffusion, respectively, floyd stein, sierra, Stenenson filter)
