This a matlab program for synthetics of slab waveguide for TM modes.

在傅立叶变换光学中夫琅和费衍射场的强度分布就等于屏函数的功率谱。因此我们可以直接将光屏进行傅立叶变换，再处理得到衍射图样。(In the Fourier transform optics, Fraunhofer diffraction field intensity distribution is equivalent to the power spectrum display function. Therefore, we can directly Guangping Fourier transform, and then to handle any diffraction pattern.)

说明：  主成分分析： (1) 根据指标的属性将原始数据统一趋势化 (2) 利用协方差、相关系数矩阵进行主成分分析，判断可否用第一主成分排名？(Principal component analysis: (1) Unify and trend the original data according to the attribute of the indicator (2) Using covariance and correlation coefficient matrix for principal component analysis, can we use the first principal component ranking?)

整流二极管1N4007的非常完整资料，介绍了典型的参数和性能(1N4007 Rectifier Diode very complete information on the typical parameters and performance)

several files allowing to do a LDPC code optimization based on exit charts

用FEMALE.TXT和MALE.TXT的数据作为训练样本集，建立Bayes分类器，用测试样本数据对该分类器进行测试。(With the older MALE. TXT. TXT and data as the training sample set, establish Bayes classifier, test sample data with the classifier for testing. )

说明：  讲述LTE关键技术及其发展趋势的详细说明，很有前沿性，很有可读性(About LTE key technologies and development trends in details, very cutting-edge, very readable)

Matlab中如何检验数据是否符合某种分布，例如:正态分布、γ分布、泊松分布、指数分布、rayleigh分布。(Matlab how to verify the data meets certain distribution, for example: the normal distribution, the γ distribution Poisson distribution, exponential distribution, rayleigh distribution.)

实现输入一串数字，然后matlab可以将数字对应的蜂鸣音播放出来（类似于电话的拨号）(Achieve input a string of numbers, then you can figure corresponding matlab beep play out (similar to dial-up phone))
