数值分析中的三次样条插值算法，追赶法解方程算法的MATLAB实现函数和测试数据。样条插值算法支持一阶导数边界条件、二阶导数边界条件和周期边界条件三种不同边界条件类型。-Numerical analysis of the cubic spline interpolation algorithm, the catch-up method of solving equations algorithm in MATLAB functions and test data. Spline interpolation algorithm supports three different boundary conditions types of boundary conditions of the first derivative, second derivative boundary conditions and periodic boundary conditions.
