theSecond

可以实现十几位整数的四则运算，效率也较好(Four operations can be more than a dozen integer,and the efficiency is better)

说明：  经过个人修改的matlab科学计算程序，供初学者使用(MATLAB scientific computing and visualization simulation literature amended program can achieve numerical conversion between)

C++实现的FFT，详细，简单，内含多个测试类(using C++ implements fft，including serials class)

FFT快速傅里叶变换，用于数字信号处理，大大提高了运行速度，节省内存开销。C语言实现(FFT fast Fourier transform for digital signal processing, greatly improving the speed and save memory overhead. C language)

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.)

开发环境没有可选项，fortran90,Fortran_90_and_Computational_Science-_codes(Computational Science codes by fortran90 )

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

EMD分解C语言算法，内含EMD分解所需的三次样条插值C语言算法。(EMD decomposition algorithm C language, containing the decomposition EMD cubic spline interpolation algorithm C language.)

巨正则系综蒙特卡罗算法的源程序；可以用来进行吸附等分子模拟；最大的好处在于可以插入或删除原子(Grand canonical ensemble Monte Carlo algorithm source can be used for adsorption, molecular simulation biggest advantage is that you can insert or delete atom)

C语言版,机载SAR回波仿真程序，附有FFT和复数库，以及位图显示模块。本程序注释详解，对加深SAR的理解有很好的帮助(C language version, airborne SAR echo simulation program with FFT and complex database, as well as bitmap display module. Detailed notes of this procedure, for deepening the understanding of SAR has a good assist)
