我编写的提取心音信号的包络，matlab编写

我做的关于数字信号处理的matlab实验。主要是卷积运算的实现和滤波器设计。(I have done on the digital signal processing matlab experiment. Is mainly the realization of convolution and filter design.)

说明：  人工创建一个红色的圆球,根正苗红的圆球，(make a red ball)

matlab学习，适合初学者对matlab软件进行学习(matlab learning software for beginners to learn matlab)

5种改进的和声搜索算法的程序实现，其中两种是本人提出的并且公开发表的论文的程序实现(The improved harmony search algorithm program, two of which I proposed and published papers program)

说明：  视频水印，在每一帧视频帧上嵌入水印，不可见性良好(video waterMarking,embed the watermark on each frame of video,invisibility is mediocre)

说明：  增量式PID matlab控制例程，可以尝试调节Kp/Ki/Kd(Incremental PID matlab control routine)

本程序利用matlab，计算视频中标定板的位置，并将其位置显示在三维坐标中。

三相异步电机调速仿真模型，包含变频调速、矢量控制，串电阻调速模型等(Three-phase induction motor simulation , including the Frequency Control, vector control, speed control model series resistor)

求人体信号的一个周期序列的CZT和FFT计算结果比较。是很好的程序，可以直观的看到效果。(Order to signal a cycle of the human sequence comparison CZT and FFT calculations. Is a very good program, you can see the visual effect. The body s signals.)

遗传算法，可以用来求解在一定范围内的函数的最值，进行函数优化(Genetic algorithms can be used to solve a range of functions in the most value for function optimization )
