多天线人之中继网络的研究，很好的一篇论文，我自己受益匪浅(The multi-antenna relay network of people, very good paper, I benefited)

有大量的方程是无法直接求出解析解的，用matlab可以方便的得出复杂方程的数值解，附有pps的讲解说明(There are a lot of equations can not be directly obtained analytical solution of the numerical solution of the complex equation matlab can come and with pps explain instructions)

厄米高斯光束的仿真软件，可仿真基本的厄米高斯光束及其光斑。(Hermite Gaussian beam simulation software can simulate basic Hermite Gaussian beam and spot.)

用于分类的主判别变量算法(principal discriminant variate algorithm) ( principal discriminant variate algorithm for two classes, x1 and x2. x1 is the training samples in the 1st class with each column being the spectrum characterizing the corresponding sample. x2 is the training samples in the 2nd class with each column being the spectrum characterizing the corresponding sample. lamda is the penalty weight defining the balance between FLDA and PCA. dvnum is the number of principal discriminant variates to be computed. A defaul value for dvnum is 2. dv is the principal discriminant variates. scores is the matrix with each row being the scores of the samples on the corresponding principal discriminant variate. xmean is the mean spectra of the sample, which was used for mean-centering the data in training and prediction. )

数学应用中的25个matlab程序，绝对经典，对初学matlab编程有很好的参考价值。(Mathematical applications in matlab program 25, an absolute classic, matlab programming for beginners have a good reference value.)

　　本文提供了一个分析　　复杂的动态显示当前模式控制　　开关电源转换器。电流型控制的提高　　转换器与非线性分析和研究　　离散建模方法已被使用。通过改变　　电路参数、混乱和复杂的行为　　分歧发生在开关电源转换器。为　　增加稳定period-l操作范围,坡道　　已经被改变其使用和补偿方法　　转换器的边坡,其效果将被显示。最后, 　　最大平均Iyapunov指数不同的斜坡上　　审查和模拟。(The present article provides an analysis of complex dynamics displayed by current mode controlled switching dc-dc converter. Current-mode controlled boost converter has been studied with nonlinear analysis and the discrete-time modeling approach has been used. By changing circuit parameters, complex behaviors like chaos and bifurcation occur in the switching dc-dc converter. For increasing stable period-l operation range, the ramp compensation approach has been used and by changing its slope, its effect in the converter will be shown. Finally, the largest average Iyapunov exponent for different slopes is reviewed and simulated)
