说明：  这是一个matlab的直方图均衡程序，先读入一副彩色图像，将其转成灰度图，输出该图的直方图，做均衡以后再次输出，可以看到均衡后图像直方图比较均匀了。(this is a histogram program based on matlab)

it is the program for echo cancellor using the rls algorithm

MATLAB计算机视觉与深度学习实战-运行视频(As a biological technology, face is difficult to be stolen and infection-free. In addition to that, it enjoys the authentication concealment and is never forgotten. Therefore, authentication based on face recognition will become the mainstream of future development. It has important and extensive application in various fields, and is also a hot topic at present biological characteristics identification technology research. Under the non-restrictive condition, the face recognition rate is not high, and its accuracy needs to be further improved. In this paper, the following aspects is analyzed)

三相桥双极性PWM控制Simulink仿真，叠加一些其他信号，另加一滤波器观看PWM经过低通滤波后的波形，适合电力电子初学者(Three-phase bridge bipolar PWM control Simulink simulation, superimposed a number of other signals, plus a watch PWM filter through after the low-pass wave filter for power electronics for beginners)
