说明：  非线性有限元程序，二维， 非常好用的啊！！！！！！！！！！！！！！！！！！！！！！！！！！！！(nonliear fem)

基于欧式距离的KNN分类方法,本代码只适用于将数据分为三类。类数更多或更少需要简单的调整。(KNN classification method based on Euclidean distance)

这个是基于Rosin论文编写的一个Rosin算法，(This is based on a written paper Rosin Rosin algorithm)

分析了正弦信号分辨率问题，当采样频率相同时，点数越多，分辨率越高，频谱特性误差越小( Analysis the problem of resolution in a sinusoidal signal.When the sampling frequency is the same, the more points,the higher the resolution,and the error spectral characteristic is smaller.)
