说明：  L-曲线法是反问题正则化方法中的参数选取中的重要方法，本程序给出了如何恰当选取其中的参数！(L-curve method is the inverse problem regularization method of parameter selection in an important way, this procedure is given on how to properly select one of the parameters!)

本代码是光子晶体光纤切面的光强分布仿真程序，对搞光子晶体的同行很有帮助。(the code is photonic crystal fiber plane, the intensity distribution simulation program to engage in peer photonic crystal helpful.)

外国SU里的偏移处理程序，TXT格式，对于高偏移处理的研究很好。(Offset program in the foreign SU, TXT format, good for the study of the high migration.)

针对LDPC码在理论和实现两方面分别进行了较深的研究。深入了解了LDPC码编码方法、译码方法以及性能等知识，重点研究了用MATLAB如何构造奇偶校验矩阵、如何编码和如何解码的算法，而且实现了在相同码率、信噪比下LDPC码性能与卷积码性能的对比。(LDPC codes for both theory and implementation were carried out deeper study. In-depth understanding of the LDPC coding method, decoding method and performance of such knowledge, focuses on how to use MATLAB parity check matrix structure, how to encode and decode algorithms how, but also achieved at the same rate, SNR LDPC codes Comparative performance and convolution code performance.)
