说明：  可用于层次分析法比较评价，主函数输入初始矩阵，调用层次分析函数(It can be used for comparative evaluation of analytic hierarchy process. The main function input the initial matrix and call the analytic hierarchy process function.)

说明：  用fortran 70实现数值积分，并实例计算了三个函数，导出了积分值和误差(The numerical integration is realized by FORTRAN 70, and three functions are calculated with examples. The integral values and errors are derived.)

二维有限元源代码，为位势问题基本代码，具有一定实用性(Two-dimensional finite element source code for potential problems basic code, with some practical)

二维TM波的FDTD(2D TM wave under two-dimensional TM wave of FDTD)

说明：  计算超短脉冲非线性传输的一个比较成熟的M文件(Calculation of nonlinear transmission of ultrashort pulse of a more mature M documents)

这是利用FFT分析相位差的程序，具有一定的参考价值！(This is done using FFT analysis phase of the program, has a certain reference value!)

用于求解一维气体动力学的欧拉方程代码，采用戈东诺夫格式，显式推进，可仿真非定常激波管(For solving one-dimensional Euler equations of gas dynamics code, using Godunov format, explicit advance, can simulate unsteady shock tube)

用三元组表为结构，实现稀疏矩阵的加法并输出。(Achieve sparse matrix addition)
