经验模式分解程序（matlab）可以对输入信号进行经验模式分解(Empirical mode decomposition process (matlab))

This demo tracks cars in a video by detecting motion using optical flow. The cars are segmented from the background by thresholding the motion vector magnitudes. Then, blob analysis is used to identify the cars.

物理公式代码库 常见的物理公式可以从库中直接调用 方便(Physics formulas physics code base common formula can be called directly from the library to facilitate)

利用拉普拉斯变换的思想，通过对数据进行差分，近似得到拉普拉斯变换后的结果，然后检查正负交换的位置，则此为极值点位置，利用此思想得到极值点的位置。(Using the ideas of Laplace transform of the data by the difference approximation get results Laplace transform, and then check the position of the positive and negative exchange, this is the extreme position, take advantage of this thinking of getting extreme points location.)

这个是对一般信号进行快速傅里叶分析。并画出其幅频图和相频图。与原信号进行比较(This is the general signal fast Fourier analysis. And draw the amplitude frequency and phase frequency diagram. Comparing with the original signal)

MATLAB中也同样有许多有意思的实例，为提高读者对MATLAB和Simulink的兴趣，特举部分以供参考。(MATLAB, there are also many interesting examples, in order to enhance the reader' s interest on MATLAB and Simulink, special give some for reference.)
