Description: 代入法的启发示搜索
我的代码实现是：按照自然语言各字母出现频率的大小从高到低（已经有人作国统计分析了）先生成一张字母出现频率统计表（A）--------(e),(t,a,o,i,n,s,h,r),(d,l),(c,u,m,w,f,g,y,p,b),(v,k,j,x,q,z)
，再对密文字母计算频率，并按频率从高到低生成一张输入密文字母的统计表（B），通过两张表的对应关系，不断用A中的字母去替换B中的字母，搜索不成功时就回退，在这里回朔是一个关键。
-generation into a search of inspiration I said a code is : According to the Natural Language alphabet frequency of the size of precedence (has been for the State Statistical Analysis), Mr. into an alphabet frequency tables (A )--------( e), (t, a, o, i, n, s, h r), (d, l), (c, u, m, w, f, g, y, p, b), (v, k, j, x, q, z), again close to the mother language calculated frequency and frequency input precedence generate a secret letter to the mother TAB (B), Table 2 by the corresponding relations, use of the letters A to B to replace the letters of the alphabet, when unsuccessful search regression, Here is a retrospective key.

Description: newmark法计算响应的收敛问题
程序是王勖成书中的程序
质量、刚度矩阵的存储形式已经由原来的半带宽存储改为全矩阵存储的形式，特殊需要
质量、刚度矩阵应该没有问题，因为计算出来的固有频率是正确的-Newmark method in response to the question of the convergence process is Wang Xu procedures into the quality of the book, stiffness matrix from the original storage format has been changed to the semi-bandwidth storage full matrix storage form of the special needs of quality, stiffness matrix should not be a problem, as calculated natural frequency is correct Platform: |
