实验一：三次样条插值（P56，例6）
一、实验目的：
1) 掌握三次样条插值的运用
2) 了解拉格朗日插值在高次上的误差
二、实验环境：Matlab6.5
三、实验内容：
1) 给定函数f(x)=1/(1+x2)，-5<=x<=5，节点xk=-5+k，(k=0,1,2…10)，用三次样条插值求S10(x)，S10’(-5)=f’(-5)，S10’(5)=f’(5)。
2）作原函数f(x)，拉格朗日插值函数Ln(x)，三次样条差值函数Sn(x)。画出三个函数的图像，比较它们的区别。
(Experiment I: cubic spline interpolation (P56, cases of 6) First, the experiment was: 1) cubic spline interpolation to master the use of 2) understanding of Lagrange interpolation in high-error second, experimental environment: Matlab6 .5 c, experimental elements: 1) a given function f (x) = 1/(1+ x2),-5 <= x <= 5, node xk =- 5+ k, (k = 0,1,2 ... 10), using cubic spline interpolation for S10 (x), S10 (-5) = f (-5), S10 (5) = f (5). 2) for the original function f (x), the Lagrange interpolation function Ln (x), cubic spline difference function Sn (x). Draw the three functions of images, compare the difference between them.)

假设微电网中有风、光、微型燃气轮机、蓄电池，且已知各时段负荷需求；考虑各机组运行成本、燃料成本、与污染物处理成本。该程序可解决在孤岛运行模式下，各机组出力如何分配才能达到经济最优的问题。(It is assumed that there are wind, light and micro gas turbines and batteries in the microgrid, and the load demand is known at each time period. The operation cost, fuel cost and pollutant disposal cost of each unit are considered. This program can solve the problem of how to allocate the power of each unit in the mode of island operation to achieve the best economy.)
