解决微分方程组/代数方程组Fortran算法-This code solves a system of differential/algebraic equations of the form G(T,Y,YPRIME) = 0.

手写分类识别，是个很好的程序，希望大家能用上-Handwriting classification and recognition, is a very good program, hope everyone can be on the

这是用C语言编写的简单的用Vt码做的贪吃蛇小游戏，游戏主要是在终端界面玩，未完尚待完善，望各位大神多提宝贵意见

一种好的改进遗传算法function [opy,optimy]=GA(pt,gennum,psize)% 输入参数：% pt       m*n的加工时间矩阵（n是工件数目，m是机器数目）由已知给的T矩阵，可得n=100,m=10% gennum   迭代的次数（代数）% psize    种群的规模大小%输出参数：% opy       最优的Makespan值pc=0.9;%交叉因子pm=0.1;%变异因子[m,n]=size(pt);current_gen=1;%current_gen means the current generationnewgen=zeros(psize,n+1); %mewgen is the new generation of the populationnewgen(1:psize,1:n)=rand(psize,n);%主种群初始化，0-1之间的随机数 %Generalize the initial groupfather=zeros(2,n); %father is used to store the two genes for crossover and mutation avgen=zeros(1,gennum); %avgen is the matrix of the average of all the generationsoptimx=zeros(1,n);optimy=ones(1,gennum);%Generalize the initial groupfor i=1:psize    [Ya,pop(i,1:n)]=sort(newgen(i,1:n));%种群排序，实数编码转换为自然数编码 随机生成的0-1之间的小数进行排序然后取每个从小到大数对应的位置    newg

大数阶乘，能计算超大数的阶乘，算法简单易懂，采用数组存储计算结果！本算法也可以改进采用链表存储结果！-majority factorial, which calculates the number of super factorial, the algorithm is simple to understand and use storage arrays results! The algorithm also can be improved using Chain store results!

一个用来计算每年1月1号星期几的c小程序！实现比较简单，其实就是计算闰年的小程序，不过小程序可能有点小bug，希望大家包含！-one used to calculate the annual January 1 several weeks of c small program! Achieving a relatively simple calculation of leap year is actually a small, but a small program might have a small bug, we hope that contain!

本程序新建complex类，并将数学库里的“+”“-”“*”“/”符号运算进行重载，使其适用范围从实数扩展至复数。-the new complex procedures category, Mathematics, 13-17 and the """-""*""/" symbol for heavy computation, from the scope of the application is extended to a number of plural.
