自己写的频率谱细化程序，应用了两种方法实现，经过测试效果不错，拿来和大家分享。(there are two programs that make the Zoom_fft come true.)

说明：  matlab求解常微分方程在机械设计中的应用(matlab solving ordinary differential equations in mechanical design)

我用MATLAB做的增广矩阵法系统参数辨识(I use MATLAB to do the Augmented Matrix Method system parameter identification)

该程序完成的是通过使用所提供的链码（一种方向码）来画出链码所表示的轮廓。所画轮廓在原图上是黑色的线。(the code is used for draw the outline of the region of interest which is show by the chaincode)
