有加减乘除和括号运算功能的计算器，还可以算三角函数(calculator including plus，minus,mutiply,add)

说明：  二维光子晶体弯曲波导的fdtd程序,matlab语言 ,TE波, PML边界条件,平面波光源(Two-dimensional photonic crystal waveguide bend the FDTD program, matlab language, TE wave, PML boundary conditions, plane wave light source)

可以实现求解微分方程组的数值解，在func中输入需要计算的微分方程组，运行主函数即可(Can be achieved to solve the numerical solution of differential equations, the input need to calculate the differential equations in the func to run the main function can be)

vc++实现编译原理中的LL(1)文法的编译过程,非常好用.(vc realization of the principle of compiler LL (1) grammar compiler course, very handy.)

说明：  用LBM代码编写的由于温差而产生的自然对流小程序(As with the LBM code written in natural convection resulting from temperature applet)

之前找不到合适精度的log2x函数的定点化源码，经过实现并验证后，发上来大家一起学习(fixed version for log2x)

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

我自己用c语言写的64点基4FFT算法，在visual c++ 6.0环境下编译通过。同matlab结果一致。(My own use C language to write the 64 based 4FFT algorithm, in visual c++ 6 compiler environment through. Results consistent with matlab.)

计算风力机的转换功率的算例 根据流体力学激盘素理论推出 最大转换功率不可能超过0.47(cofficience of power change from wind energy to eletricity energy.)

基因的FFT变换，可以快速得出外显子的位置(Transform FFT of the gene can be quickly drawn to the location of exon)
