最大概然估计拟合直线，简单的使用最大概然估计拟合了直线，文件中给出了两张图片(MLE fit line（MLE for fitting a line pair）)

说明：  利用FDTD方法模拟普通光子晶体光纤中模场变化的情况，为主程序，可以为学习FDTD模拟PCF的学习者提供一定参考和学习。(Ordinary FDTD simulation using photonic crystal fiber mode field changes in the situation, the main program, you can learn from FDTD simulation for the PCF to provide a reference of learners and learning.)

可以计算光纤与波导耦合的1db容差，只需要算出几组耦合值，然后倒入到matlab 程序中便可自动得到1db 容差。(calculate the tolerance of 1db，it is evry eazy for user to use。)
