本程序实现了一个简单的非线性约束最优化问题，仅供参考(This program implements a simple nonlinear constrained optimization problems, for reference only)

自己编写的求可达矩阵，层次划分 代码.使用时，替换已有矩阵，即可运算！ (I have written for reachability matrix, the level of classified code. Use, replace the existing matrix, computing can be!)

是用MATLABA编写的遗传运算发的一个小程序 挺好用的 大家(MATLABA is prepared by the genetic operator issued a small procedure very well, we try to use)

说明：  四级四阶龙格库塔格式，求解微分方程的好算法。(Four fourth-order Runge-Kutta format, a good algorithm for solving differential equations.)

采用相互垂直的两个振子构成圆极化天线的FDTD程序．可以计算其圆极化波瓣宽度等天线指标 (perpendicular to each other using the two oscillator constitute a circularly polarized antenna FDTD procedures. Can calculate its lobed circular polarization antennas width indicators)

cpsd 单独子函数，可编译后直接应用于自己的程序，方便快捷，使用fftw库(cpsd separate sub-functions can be applied directly after compiling its own procedures, convenient use fftw library)

计算流体力学重要算法 simple算法计算顶盖驱动流动。(An example for using SIMPLE algorithm to computing lid driven flow in CFD)
