基于fdtd算法利用matlab软件编写的计算问题空间的程序，适合光电子和晶体等领域(Based on FDTD algorithm using matlab software to write the calculation problem of the space program, suitable for optoelectronic and crystal, etc)

最速下降法是一种沿着N维目标函数的负梯度方向搜索最小值的方法。该程序是用最速下降法求无约束最优化解。(Steepest descent method is an N-dimensional objective function along the negative gradient direction of the minimum search method. The program is used steepest descent method for unconstrained optimal resolve.)

经典匹配追踪程序。附带经典lena图像、并对其进行处理。(Classic match-tracing program. With classic lena image and its processing.)

眼图的实现程序实例，使用matlab2008编写，仅供参考(The eye diagram to achieve instance, to use matlab2008 to write, for reference only)

总体平均经验模态分解EEMD程序可用于信号进行时频分析，比EMD程序更好用。(The overall average empirical mode decomposition EEMD program can be used to signal time-frequency analysis, better than the EMD program.)
