BEM

说明：  借助python3计算偏微分方程组，并作出相应图形，代码简单易懂，方便修改(Calculate partial differential equations)

说明：  你输入一个长方体的长和宽以及高，就可以输出他的面积(input height，width，length，output volume)

说明：  some article about Bayes Thinking

有直接法,间接法,Bartlett法,Welch法(有????? ????? Bartlett ? Welch )

说明：  FFT，整型数据代替浮点型数据 本程序是搜集资料并加上自己的分析，整了很长时间才测试通过的FFT程序，运行时间和所占内存方面都比较满意。(FFT, integer data instead of floating point data This program is to collect data and add their own analysis, the FFT program passed the test for a long time, the running time and memory occupied are relatively satisfactory.)

说明：  umat abaqus plasticity

说明：  此文件为源代码，经过多次验证可行。将代码输入lingo就可以运行(Immune algorithm to solve the maximum clique problem source code of this file, feasible after several validation. Matlab code input can run.)
