自己写的广义LDPC的程序，包括编译码，其中最重要的是一码算法，用的是chase算法，有很好的性能，希望可以跟大家交流改进(Generalized LDPC write procedures, including the encoding and decoding, most important of which is a code algorithm, using a chase algorithm has good performance, hoping to improve communication with everyone)

FDTD Finite-Difference Time-domain in free space no ABC FDTD(t) runs FDTD for time t. FDTD implements the FDTD/staggered leapfrog scheme over time 0-max_time and space 0-max_space. This program simulates a gaussian pulse in the grid specified with max_time and max_space. The pulse is sent from the center of the problem space and disperses in both directions -Kira Heater

This program is written to compute the attitude angles roll-pitch and yaw through Direction Cosine Matrix Error dynamics.

说明：  蚁群算法求解TSP问题,非常简单，绝对可用(ant swarm to solve the problem of tsp )

一些非常实用的神经网络实例，是用matlab语言编写，值得学习和借鉴！(Some very practical instance of the neural network, using matlab language worth learning!)

（1） 本系统用到四种神经网络对漏电嫌疑系数进行预测，分别是BP神经网络、RBF神经网络、GRNN神经网络、Elman神经网络，通过对神经网络结构参数的设置和调试，可以得到很好的预测效果，实际值和预测值之间的误差能达到5 以内。 （2） 本系统使用matlab做GUI界面，在界面上就可以分别对这四种神经网络的结构参数进行设置，从而可以调整神经网络的结构，达到较好的预测精度。 ((1) The system used four neural network to predict the suspected leakage coefficient, respectively, the BP neural network, RBF neural network, GRNN neural network, Elman neural network, the neural network structure parameter setting and commissioning, can get very good prediction, between the actual and predicted values ​ ​ of error of less than 5 . (2) the use matlab to do the GUI interface, the interface can each of these four neural network structure parameters set, the structure of the neural network, which can be adjusted to achieve better prediction accuracy.)

It is code for mir testing
