分别以单精度和双精度数据类型用以下近似算法分别计算π的近似值，要求结果具有4位有效数字(calculate pi with single-precision and double-precision respectively)

一维 问题，即激波管问题，是一个典型的一维可压缩无黏气体动力学问题，并有 解析解。对它采用二阶精度 两步差分格式进行数值求解。(Use MacCormack difference scheme for solving a two-dimensional shock tube problem)

用C++来实现NEWTON迭代法解非线性方程算法数值分析，是数值分析里典型的一个算法。(In C++ to achieve NEWTON iterative numerical algorithm for solving nonlinear equations, numerical analysis is in a typical algorithm.)

圆周卷积滤波器，可清晰见到实际滤波器的算法(Circular convolution filter, can clearly see that the actual filter algorithm)
