说明：  低密度奇偶效驗碼利用硬式解碼再經過bsc通道下的錯誤率(Low-density parity codes using hard and then after bsc channel decoding error rate under the)

用矩量法（双位方程）分析半波振子天线的电流分布，方向性图(anlyse linear antennas with MOM)

在Matlab下，实现大地坐标之间互相转换。(In Matlab, to achieve mutual conversion between geodetic coordinates.)

这个代码可以画出一个具有一定倾角的规则长城(This code can draw a certain angle with the rules of the Great Wall)

利用神经网络进行语言特征的识别，很有用的代码，希望对大家有用(Neural network is used to identify the characteristics of language, is very useful code, hope useful for everyone)

There are 5sample files of qpsk, ofdm, scfde, alamouti and space time codings. those of 5samples can be useful for using matlab user.

有约束2a+b^2+tan(c)=15 目标函数a*exp(b/x)+c=y 的最小二乘解(Binding 2a+ B ^ 2+ Tan (c) = 15 the objective function a* exp (b/x)+ C = y the least squares solution)

说明：  用matlab符号对象求解非线性方程组，进行函数绘图(solve nolinear equations used matlab)

本程序不能编译除大小写字母之外的编码 本程序需事先建立字母权值文后件才可运行 本程序从文件中读入文字，编译后写入文件，所以屏幕上不会直接出现答案(not build this program in addition to case-insensitive outside of the coding process required prior to the establishment of the letters after the value of the text pieces can Win OK this program read from the file into the text, compiled into the paper, not directly on the screen appeared the answer)
