说明：  插值问题 ，多项式插值 会写 Lagrange 插值多项式，理解插值基函数的形式与功能 会用误差公式 分段线性插值 分段三次插值和样条，了解两种插值方法需要满足的条件，不要求理解原理和插值 多项式的具体形式和求解方法，要求会用 Matlab 命令实现 数值积分问题 梯形公式，辛普森公式，复合梯形公式，复合辛普森公式，上述公式的误差分析 插值型求积公式 代数精度（理论分析） quad 命令， 自适应步长的复合辛普森公式
(One Interpolation problem, polynomial interpolation Two Write Lagrange interpolation polynomials, understand the form and function of interpolation basis function, and use error formulas. Three Piecewise linear interpolation Four Piecewise cubic interpolation and splines, understanding the conditions of the two interpolation methods, do not require understanding the principle and interpolation The concrete form and solving method of polynomial require to be realized with the command of matlab. Five The numerical integration problem Six Ladder formula, Simpson formula, compound trapezoid formula, compound Simpson formula, error analysis of the above formula Seven Interpolating Quadrature Formula Eight Algebraic Accuracy (Theoretical Analysis) Nine Quad command, compound Simpson formula with adaptive step size)
