基二、基四、基八 FFT变化源代码，有详细注解(Second base, the base four or eight FFT-based changes in the source code, detailed comments)

说明：  fortran弹塑性分析程序，很有用的啊！(fortran plastic analysis program, very useful)

最小二乘法数据处理软件，翻遍计算的程序，应用于各种优化算法(math caculateor)

提供函数能进行1维2维的FFT，输入输出的序列长度应为2的整数次方倍(Provides functions can be one-dimensional two-dimensional FFT, sequence length input and output should be an integer power of 2 times)

有限元n维实体材料单元，仅供科研用途，拒绝商业使用(N-dimensional finite element solid material element, for scientific purposes, refusing commercial use)

说明：  用刷选法求出100之内的素数。并输出数有多少个。(100 prime number is calculated by the method of selection. And the output count how many.)

本算法是求取点到曲线的距离，希望对大家有帮助(the algorithm is to strike a point of the distance curve, and I hope to be helpful)

分享一个外国人编写的FDTD程序,可以用来计算微带线和微带贴片天线,程序中采用的是均匀网格划分,但也可以在容易地在它基础上改写成非均匀网格.其边界条件与Sheen的程序不同,这里采用二阶技术.(Prepared to share a foreigner FDTD procedures, can be used to calculate the microstrip lines and microstrip patch antenna, the procedure used is uniform mesh, but can also easily rewrite it into the basis of non-uniform grid. its boundary conditions with different processes and Sheen, where second-order technology.)

1.数据时随机产生的（产生1000个随机数），进行排序2.每一次数据排序之后，都可以看到排序的移动，交换次数以及排序的时间。 (1. After randomly generated data (generated 1000 random numbers), every sort 2. Sort the data, you can see the sort of move, switching times and sort of time.)

CSharp用于卫星广播星历计算和精密星历计算(Used for satellite radio star calendar calculation and precision star calendar calculation)
