一是利用计算机对正整数进行素因子分解认识素数，通过运用筛法与试除法寻找一定范围内的素数，体会到筛法比试除法有效但无法找出所有素数；二是通过若干特殊形式的素数的研究，寻找素数生成公式，发现一些结论；三是借助于非线性拟合技术，观察素数分布规律，利用其研究有关数论问题。(The first computer was used to prime factor decomposition of positive integers understanding of prime numbers, through the use of screening method and trial division to find prime numbers within a certain range, the division experienced a test of an effective screening method but can not identify all the prime numbers second is through a number of special form of prime numbers research, looking for prime number generation formula, found that some of the conclusions third, by means of non-linear fitting technique to observe the distribution of prime numbers, using their research on number theory problems.)

有限时域分析方法的源代码，希望对大家有用处哈~~~(finit time analyze)

说明：  基于FDTD方法，对光子晶体进行数值模拟，该程序只针对TE模，能直观的观察传播情况。(Based on FDTD method, numerical simulation of photonic crystal, it is only for the TE mode can be directly observed the spread of.)

利用prewitt、sobel、roberts边缘检测器进行边缘检测(Use prewitt, sobel, roberts edge detector for edge detection)

先得到一个定位初始估计值，再利用建立最大似然方程对这个定位初始估计值进行修正，从而得到更优定位结果值，方法更接近于最大似然方法。(Get the a position initial estimate, re-use to establish the maximum likelihood equations corrected for positioning the initial estimates, resulting in better positioning the resulting value is closer to the maximum likelihood method.)
