qrs波算法，一个用maltab写的简单的算法。确定q,r,s的位置。(ECG SIMULATION USING MATLAB)

二阶自抗扰控制器算法中跟踪微分器、扩张状态观测器和非线性误差反馈率的.m文件和simulink仿真图例。(Second-order tracking differentiator ADRC algorithm, the extended state observer and nonlinear error feedback rate. M file and simulink simulation legend.)

用matlab实验水平集，运用到灰度图像上面可以得到的很好的分割效果，下载后可以直接运行得到结果(Matlab experiment level set, apply to the gray image, it can get very good segmentation effect can be run directly after download the result)

面向对象程序设计的优点表现在实现对现实世界客体的自然描述、可控制程序的复杂性、可增强程序的模块性、可提高程序的重用性和可改善程序的可维护性等方面。(The advantages of object-oriented program design performance in achieving a natural description of real world objects, and can control the complexity of the program, can enhance the module of the program, program would improve the reusability and maintainability can be improved, and so on. )

This code use Principle Component Analysis(PCA)for feature extraction

The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform. For Haar transform, the transformation matrix H contains the Haar basis functions hk(x). They are defined on a continuous, closed interval, x -[0, 1] for k = 0,1,2 ...,N -1 where N = 2n.( The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform.

画任意曲线的包络线，目前matlab里面还没有关于画曲线包络线的(plot the envelope of curve)

说明：  matlab中一些重要的课件和资料，比较有用啊！(matlab courseware and some important information, more useful ah!)

超分辨率的基础书籍，要学习超分辨率的同学可以看看，很好的(Super-resolution based books, the students should learn to look super-resolution, very good)

说明：  自己做的基于Matlab/Simulink 的系统仿真技术与应用一书的配套实验(Make their own based on Matlab/Simulink for System Simulation Technology and Application of a book supporting the experimental)
