In this course we present the basic principles of Bayesian statistics (an alternative to "orthodox" statistics). We start by learning how to estimate parameters for standard models (normal, binomial, Poisson) and then get acquainted with computational methods (MCMC) and software (WinBUGS) that can solve complicated problems that arise in real applications.

这组代码模拟了整个信号的编码，调制，解调，译码在无线通信，其中包括A-law扩展，PCM和的2PSK调制解调的技术过程。(This collection of codes simulates the whole signal encoding, modulation, demodulation, decoding process in wireless communication, which involves the techniques of A law companding, PCM, and 2PSK modulation and demodulation.)

说明：  该书的英文版是国外电子信息类优秀教材，国内外很多学校采用它作为教材，基本上是学习matlab的经典和权威书籍了，但是中文修正版没有（虽然是网友自己翻译的），但还不值得一看的。(The English version of the book is the best type of foreign electronic information materials, both at home and abroad, many schools use it as teaching material, is basically a classic learning matlab and authority of books, but there is no Chinese version of the amendment (although the users own translation), but also not worth a visit.)

关于基因分类的文章和源代码，可以运行,这是关于研究生数学建模的(gene gene gene gene gene )

最近邻插值算法matlab实现，内含程序和说明，非常详细(The implementation of the nearest neighbor interpolation algorithm matlab)

文件多自由度.m为单独的文件，单独执行即可，可以得到一个3自由度的系统受到脉冲作用的结果。 文control.m,plotresult.m,duoziyoudu.mdl为一个完整的程序，先执行control.m，而后执行duoziyoudu.mdl文件，最后plotresult.m文件画出结果。使用的是kobe地震波.(Document multi-degree of freedom. M as a separate document, a separate implementation can, you can get a 3-DOF system are the result of impulse. Text control.m, plotresult.m, duoziyoudu.mdl for a complete procedure, the first implementation of control.m, then the implementation of duoziyoudu.mdl documents, the final document drawn plotresult.m results. Kobe using seismic waves.)

说明：  FFT实现频谱图FFT实现频谱图 FFT实现频谱图FFT实现频谱图(FFT FFT FFT)

说明：  最近看到有人提问怎样用FFT实现频谱分析，我认为能够进行到频谱分析的人，对于系统研究的深度基本上已经相当不错了。本人今天做了一个例程，发给大家参考一下。 历程主要内容(signal_analyzer.rar)如下： test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。(The question was asked recently to see the realization of how to use FFT spectral analysis, I think that spectral analysis can be carried out to those who study the depth of the system basically is already quite good. Today I made a routine, distributed to Members for reference. The main contents of the course (signal_analyzer.rar) are as follows: test1.txt the first time as t, 0.001s for the step the second as the system input signal the third as a system output signal. signal_analyzer.m first test1.txt data read into workspace, and then proceed to FFT, analysis of the two signal frequency, output amplitude for input attenuation (db), the output of the input phase difference.)

可以计算两端固定的平面梁的挠度，当划分的单元越多时，梁的挠度值逐渐趋于稳定 (Can calculate the plane beam fixed at both ends of the deflection, when the division of the more units for some time, beam deflection gradually stabilized)
