此文件中有部分内容，对于初学MATLAB的人有帮助，前俩部分是一些MATLAB的基础操作，第三部分是线性方程数值解的雅克比迭代和高斯—赛德尔迭代的例子，第四部分是Gauss-Legendre积分公式，Newton-Cotes积分公式的俩个数值积分的例子，第五部分是Euler公式、向后Euler公式、改进Euler公式，二阶Runge-Kutta等方法（微分方程数值解）。(The first two parts are basic operations of MATLAB. The third part is examples of Jacobian iteration and Gauss-Seidel iteration of numerical solution of linear equation. The fourth part is examples of Gauss-Legendre integral formula and Newton-Cotes integral formula. The fifth part is Euler formula, backward Euler formula, improved Euler formula, second-order Runge-Kutta method (numerical solution of differential equation).)
