利用全波法计算同轴线的特征模式以及同轴线内的场分布，对计算电磁学全波仿真的学习很有帮助(Use Full Wave Algorithm to calculate the eigenmodes and electromagnetic field distributions of coaxial line ,it will be very helpful for the learning of computational electromagnetics)

灰色模型预测是在数据不呈现一定规律下可以采取的一种建模和预测方法，其预测数据与原始数据存在一定的规律相似性 下面程序是灰色模型GM(1,1)程序二次拟合和等维新陈代谢改进预测程序,matlab6.5 ,使用本程序请注明，程序存储为gm1.m(Gray model prediction is a kind of modeling and forecasting method which can be taken under certain regularity of data. The prediction data has some regular similarity with the original data The following procedure is the gray model GM (1,1) program quadratic fit and isometric metabolic improvement prediction program, matlab6.5, use this procedure please specify that the program is stored as gm1.m)

本代码描述了LDPC码的BP译码算法的每一个步骤，详尽。(This code describes the decoding algorithm for LDPC codes BP each step, detailed.)

相控阵天线阵列的密度加权matlab程序代码。 运行gui.m文件 lmax.m和lmin.mLinear_func.m最后几行被调用，放在和Linear_func.m路径相同的文件夹下即可 运行后command window里第一条分割线上面是第一幅图的几个值，第二条分割线上面是第二幅图的几个值。其中，peak_first是数值最大的峰值，peak_second是数值第二大的峰值(第一旁瓣)，theta_var是与 peak_first最近的左右两个谷值横坐标的距离。 因为是找半峰值点的，因为都是小数，在数组里没有正好等于主瓣幅值一半的点，只有接近一半的点，所以要设定一个范围比如大0.05或小0.05都认为是半峰值，但是有的数组里0.05的范围还是太小，所以可能报错。(Phased array antenna array the density weighted matlab program code. The last few lines of the run gui.m the file lmax.m lmin.mLinear_func.m call, same placed Linear_func.m path folder above the dividing line of the command window to run the first picture the several values ​ ​ above the dividing line several values ​ ​ of the second image. Wherein, peak_first numerical maximum peak the peak_second is the the numerical second largest peak (first sidelobe), the theta_var is the abscissa and peak_first recent about two valley distance. To find half the peak point are decimal, the array does not just equal to main lobe amplitude half points, only nearly half points, so you want to set a range, such as 0.05 or 0.05 are considered semi-peak some array, but the range of 0.05 or too small, it may be an error.)

用于添加噪声，达到去噪的目的.原始数据如果不太理想，去噪是常用的处理方法(Used to add noise to achieve the purpose of de-noising. If the original data is not ideal, de-noising is a common treatment method)
