计算杂波功率谱三维图形的程序，利用matlab平台开发(Clutter power spectrum calculation of three-dimensional graphics program, using matlab platform)

说明：  IMF能量计算，能量熵 ，EMD，matlab(IMF energy calculation)

该程序可以用来进行波谱分析，非常直观地图示频谱信息。(The program can be used for spectral analysis, spectral information very intuitive icon.)

说明：  刚刚接触图像检索的同学，对基于特征的图像检索还没有什么概念，利用这个小的程序（里面附有图像和实例）感受一下过程，对于继续研究很有帮助。(Contact with students just image retrieval, the feature-based image retrieval has no concept of, take advantage of this little program (inside with images and examples) feel the process and continue to study for the useful.)

％电影动画： ％1.首先调用moviein函数对内存初始化.创建一个足够大的矩阵来容纳一系列指定的图形（帧） ％2.调用getframe函数生成每一帧.该函数返回一个矢量，利用这个矢量创建一个电影动画矩阵 ％3.调用movie函数按照指定速度进行指定次数的播放 ％例子2：演示如何实现快速傅立叶变换（exp(j*2*pi/n)）的可视化过程( Movie animation: 1. First transfers the moviein function to the memory initialization Founds graph which an enough big matrix holds a series of assigns (frame) % 2. Transfers the getframe function to produce each This function returns to a vector, uses this vector to found a movie animation matrix % 3. Transfers the movie function according to assign the speed to carry on assigns the number of times the broadcast Example 2: How demonstrates realizes fast Fourier transforms (exp (j*2*pi/n)) the visible process )

hspice toolbox interface between hspice and matlab

说明：  Construction of 3D, a camera calibration

suitable for analysizing power quality events on real-time waveforms

This magnitude comparison uses the signless first words and the regular part2 words.
