离散傅立叶变换已成为数字信号处理的重要工具，然而，它的计算量较大，运算时间长，在某种程度上却限制了它的使用范围。快速算法大大提高了运算速度，在某些应用场合已能作到实时处理，并且开始应用于控制系统。(Discrete Fourier Transform digital signal processing has become an important tool, however, the calculation of its larger, long computing time, but in a way limits the scope of its use. Fast Algorithm for greatly enhanced speed of operation, in some applications has been able to do real-time processing and control system began to be used.)

用matlab编辑的计算振动信号的程序，设计谱分析等振动信号分析常用的分析方法(codes of vibration signal processing,which is coded in matlab.in this codes,some essential methods,for intance,spectural analysis,are presented.)

在MATLAB环境下，对图像进行哈夫曼编码。(In the MATLAB environment, the image Huffman.)

jpeg图像编码的matlab实现，主文件为jpegdemo(jpeg image coding matlab implementation, the master file is jpegdemo)

newmark法 进行时程分析 可能有个别小错误，欢迎指正...谢谢(newmark)

说明：  Chec this options of transform in matlab

模拟光滑铰链连成双摆的运动轨迹，工程力学专业课程设计(Smooth hinge placed in pairs)

实现车俩的实时监控导航，包括车流量的检测，轨迹分析等等，内容。(They realize the real-time monitoring of vehicle navigation, including flow testing, trajectory analysis, etc., content.)

关于emd的判据研究，通过它可以终止emd对分平稳信号的分解，是最新版的方法(On the EMD criterion, it can terminate the EMD pair of stationary signal decomposition, is the latest version of the method)

basic matlab. this code is to help understanding the basic operation in matlab.the file in format m-file. this good for new user in matlab.
