说明：  matlab的二维FDTD程序,PML边界(matlab two-dimensional FDTD program, PML boundary)

最优决策——用几个matlab编程的实例阐述分支定界法的思想是：首先确定目标值的上下界(Optimal decision-making- matlab programming with some examples of the branch and bound method is the idea: First, determine the target of the upper and lower bounds)

PLS 的Matlab代码,用于线性降维和回归分析(matlab source code for partial least squares)

matlab 入门教程，包含讲义和相关实例，非常实用，对于初学者(matlab tutorial, including handouts and relevant examples, very useful for beginners)

读串口信息,在matlab 环境下读出串口内容(read serial)

说明：  数字通信系统中采用基带传输和频带传输[ 1, 2 ] ,在抽样判决器之前,信号叠加了信道噪声. 本文利用 Matlab软件仿真[ 3, 4 ]分析了在判决器前叠加了高斯噪声后,信噪比与系统的误码率之间的关系.(Digital communication system using baseband transmission and band transmission [1, 2], in a sample before the decision device, the signal superimposed on the channel noise. In this paper, Matlab software simulation [3, 4] of the device in the sentence before the superposition of the Gaussian noise After the SNR and BER relationship.)

NS 仿真软件输出结果的分析。有NAM 和 MONITOR输出结果的具体分析，希望对大家有用。(NS simulation software output analysis. MONITOR output with NAM and the specific analysis, we want to be useful.)

按照给定指标采用模拟低通滤波器（巴特沃思低通或者切比雪夫低通）去逼近理想模拟低通滤波器 ，然后通过双线性变换法对模拟滤波器进行数字化，得到数字滤波器 。(According to a given target analog low-pass filter (Butterworth or Chebyshev low-pass low-pass) to approximate the ideal analog low-pass filter, then through the bilinear transformation method to digitize the analog filters, digital filters has been .)

在层状光子晶体中，由于折射率不同，能量分布不同，此程序用于模拟此效果(Layered photonic crystals, due to the different refractive index, energy distribution, this procedure is used to simulate the effect of)
