给出接收信号眼图及系统仿真误码率，可实现对二维数据的聚类，matlab开发工具箱中的支持向量机。( The received signal is given eye and BER simulation systems, Can realize the two-dimensional data clustering, matlab development toolbox support vector machine.)

有限元法计算程序，运用三角单元，进行线性插值，处理平面问题。(finite element method)

最小二乘法的c语言程序，能求解多元方程组，具有良好的效果(The C language program of the least square method can solve the multiple equations. It has good effect.)

谐波分析，加窗fft插值算法，幅值校正；多次谐波；峰值搜寻(Harmonic analysis；fft)

说明：  Optics聚类算法 OPTICS没有显示地产生一个数据集合簇，它为自动和交互地聚类分析计算一个簇次序。这个次序代表了数据基于密度地聚类结构。它包含地信息，等同于从一个宽广地参数设置范围所获得的基于密度的聚类(Optics do not show clustering algorithm OPTICS to produce a collection of data clusters, it is automatically and interactively computing cluster analysis a cluster order. This order represents the data to cluster based on the density structure. It contains in information from a broadly equivalent range of parameters obtained by density-based clustering)

说明：  Neville插值算法，xa为自变量数组，xy为因变量数组；x为待插值的自变量(Neville interpolation algorithm, xa array as variables, xy array as the dependent variable x for the independent variables to be interpolated)

说明：  Kim 的非线性有限元分析经典教材，教材很经典，对于静态有限元分析讲的很透彻，书中附有matlab代码(Kim's nonlinear finite element analysis classic textbook, the textbook is very classic, for static finite element analysis is very thorough, the book with matlab code)

说明：  数学工具： LU分解法解线性方程组，很好用(Mathematical tools: LU decomposition solution of linear equations, a very good use)
