gridconnectedmode

对给定信号进行经验模式分解（EMD），EMD基本理论和算法可参考：何正嘉.现代信号处理及工程应用 (Do empirical mode decomposition (EMD) for a given Signal.The EMD basic theory and algorithm can refer to: He Zhengjia. Modern signal processing and engineering applications)

说明：  自己写的一个计算空间时频分布的程序，可知指定Cohen类分布类型WVD，CWD，PWVD，SPWVD，BJD(himself in a room when calculating the frequency distribution procedures, we can see Cohen category designated distribution type WVD, CWD, Wigner, SPWVD, BJD etc.)

matlab绘制指南针，能够调整位置，大小和让其旋转一定角度，很实用(Matlab to draw the compass, it can adjust the position, size, and let the rotation Angle, very practical)

这是一段自己编写的基于高斯模型的matlab人脸识别代码(This is a piece I have written matlab face recognition code based on the Gaussian model)

冈萨雷斯的数字图像处理（matlab）第二版，中译本，非常实用的教材(Gonzalez, Digital Image Processing (matlab) second edition, in translation, very useful materials)

说明：  图象处理中经常用的小波分析matlab程序(Image processing are often used in wavelet analysis matlab program)

说明：  加强环的应力和位移计算程序,可以求出每隔5度位置处圆环的应力\弯矩和位移.(strengthen the stress and displacement calculation procedures, we can solve every 5 degrees positions of the stress Circle \ moment and displacement.)

this code compute a Cutter tool with optimization

灰色处理，预测模型，GM(1,1)一次累加(Gray processing, prediction model)

通过编程建立函数的最佳逼近。并且可估计它的最佳逼近误差(The best approximation of function is established by programming. And the best approximation error can be estimated.)
