用Matlab编写的相机标定程序，球去了相机参数。内附标定图像。(Prepared by the Matlab camera calibration procedures, the ball to the camera parameters. Enclosing the image calibration.)

QPSK调制 经典，非常简洁的产生qpsk的调制方法1(QPSK Modulation)

S变换的matlab源码，并应用几个信号作为例子来说明怎么使用s变换以及s变换可以用来做些什么事情。s变换是时频分析领域中一个较新的内容，现在在信号处理，地震勘探，语音识别等领域都开始了对它的应用研究，是目前的一个热点。(S transform matlab source, and apply some signal as an example to illustrate how to use s and s transform transform can be used to do things. s transform time-frequency analysis are a relatively new area of content, now in the signal processing, seismic exploration, speech recognition and other areas of the beginning of its applied research, is a hotspot.)

一个在MATLAB上编写的PCNN去除噪声的程序源代码完整，可直接使用。(Written in MATLAB on a PCNN noise removal complete source code can be used directly.)

画任意曲线的包络线，目前matlab里面还没有关于画曲线包络线的(plot the envelope of curve)

Decimal value to binary bit string converter. As long as the input is within the range, this code always generated the corresponding binary bit pattern.

利用朴实贝叶斯方法求解有关肺炎的问题。肺炎对应有四个特征：发烧、疼痛、咳嗽和血细胞异常，当确定了患肺炎与否时，四个特征条件独立。假设患肺炎与否和四个特征都可表示为Ture和False。 根据pneumonia.tex文件中的数据（500行，每行前4个数对应4个特征变量，第5个数对应患肺炎是否为真，以0表示False，1表示Ture），编写Matlab 程序 maininference.m，从example.txt中读取病人的症状信息（0表示False，1表示True，-1表示not given），并计算对应的患肺炎的可能性。所给的信息按发烧、疼痛、咳嗽、血细胞异常的顺序排列。将计算结果保存在answer.txt中。(Simple Bayesian method to solve the question of pneumonia. Pneumonia corresponding four characteristics: fever, pain, cough and blood cell abnormalities, determine the risk of pneumonia or not, the four characteristics of conditional independence. Assumptions suffering from pneumonia or not and four features can be represented as Ture and False. According to the data pneumonia.tex file (500 lines, each line of the first four numbers corresponding to the four characteristic variables, number 5 corresponds to the risk of pneumonia is true, 0 represents False, said Ture), to write Matlab program maininference. m from example.txt read the information of the patient' s symptoms (0 = False, said True, the-1 indicates not given), and to calculate corresponding to the likelihood of suffering from pneumonia. The information given by the order of fever, pain, cough, blood cell abnormalities. The calculated results is be saved in answer.txt.)

使用Matlab做出的基本调制方式的误码率曲线(Analysis of the symbol error probability for Basic Modulations )

It is a very useful matlab program to plot a 3D graph by using sfunction and it shows how to use multiplexur for x, y and z signals. Enjoy it and good luck.
