利用样条差值法，根据已知坐标，绘制整条曲线。 数学建模实例，很有用的。(Using spline difference method, based on the known coordinates, drawing the whole curve. Mathematical modeling examples, very useful.)

有关椭圆检测的一段小程序 希望大家看看 谢谢支持(Small section of the ellipse detection procedure let us look at)

高阶谱分析工具箱，强烈推荐，共计58个函数，实现了高阶谱估计的几乎全部功能。本人在这里上传的文件，仅仅为了学术交流。希望大家都有机会掌握高阶谱估计。互相切磋，共同进步！(higher order spectral analysis toolkit, strongly recommend, for a total of 58 functions, to achieve the high-end of the spectrum is estimated that almost all functions. Here, I would upload documents, only to academic exchanges. Hope we have the opportunity to acquire higher-order spectrum estimation. Peers common progress!)
