基于PSO算法优化B样条函数插值，对于给数据点，反算出控制顶点，构造B样条函数插值-Based on particle swarm optimization (pso) algorithm B spline function interpolation

输入任意采样数据，进行prony分析，给出指数形势的组合并指定后续数据点，进行数据趋势预测； http://en.wikipedia.org/wiki/Prony s_method-Anylysis the input data using prony method, and also can be used for prediction the trend of the movement. http://en.wikipedia.o

用户自定义数据点，所给函数能用最小二乘法拟合数据，并给出估计得均方误差(User defined data points, the given function can be fitted by least squares method, and the estimated mean square error is given)
