根据伊忠科、杨绍国（电子科技大学）发表的论文"分形插值图象放大和压缩编码"编程实现。(Branch, Shao- Guo Yang (University of Electronic Science and Technology) by the paper, "Fractal Image interpolation and compression coding Large" program.)

matlab 编写的下雪程序，很适合在冬天看雪花落下过程(Matlab prepared by the snow program, it is suitable in the winter to see snow falling process)

实现心电信号傅里叶变换处理、并显示原信号和处理后的信号(realized the FFT of ECG, and display the results)

Dynamic respose of single degree of freedom system using DUHAMEL integral

本程序是运用SVM来实现人脸识别算法，能直接运行且能进行二次开发(This procedure is to use SVM to implement face recognition algorithm that can run directly and can perform a secondary development)

添加噪声处理，采用波束成形技术的BER计算，pwm整流器的建模仿真，用于建立主成分分析模型，包括调制，解调，信噪比计算，线性调频脉冲压缩的Matlab程序。

说明：  给图片添加了正弦噪声，利用MATLAB源代码消除噪声。(Sine was added to the image noise, using MATLAB source code to eliminate noise.)

心电信号R波检测的函数，包括降采样，滤波，希尔伯特包络提取三个预处理步骤。其中R波根据阈值检测，相对不应期要根据具体信号适当调整.(ECG R-wave detection functions, including down-sampling , filtering, Hilbert envelope extracted three pretreatment steps. Wherein R wave detection based on a threshold , the relative refractory period should be adjusted according to the specific signal . )
