配合上传的C8051程序，通过串口接收心音数据，并通过图形显示。串口接收数据为中断方式。(With the upload process of C8051F020, through the serial port to receive heart sound data, and useing graphics to display.Received through the serial port interrupt.)

说明：  这是个混沌理论中吸引子的源代码，我们可以得出它的相图，希望对大家有用(This is a chaotic attractor theory of the source code, we can conclude that the phase diagram, we hope to be useful)

利用MATLAB软件，读取QuartusII软件里的TBL数据(use Matlab to read the TBL date of the QuartusII software)

递归函数调用，使用switch case语句实现切换编程回调结构。(Recursive function calls, switch case statement switch programming callback structure.)

一个非常不错的粒子滤波工具箱，基于面向对象的思想，matlab实现，实现非线性滤波，包括SIR，SIS粒子滤波以及相应的GUI实现(an object-oriented MATLAB toolbox for nonlinear filtering. It includes algorithms for SIR and SIS particle filters )

短时傅里叶，matlab程序，经过检验可以正常使用，(stft short-time ft)

说明：  用matlab搭建shepwm，然后通过迭代法得到更优解(SHEPWM is built by MATLAB, and the better solution is obtained by iterative method)

matlab命令大全,很好的matlab工具书(Matlab order Daquan, good Matlab tool)

matlab程序设计关于MATLAB的安装编程调试等(matlab program design on the installation of MATLAB programming and debugging)

时间计算器：分别输入开始日期和结束日期，能计算两个日期相差几天。(Time Calculator: Enter the start and end dates, it can calculate how many days they are difference.)
