根据Zeller公式计算任意日期是星期几。说明一下，压缩包中有两个是复件，是用来压仓的，以确保满足上传条件（上传文件大于1K）。(weekday for any day)

做数据处理，比如做智能诊断样本创建的时候， 如果采集信息有限，但数据量又很大， 可以选择将原始信号就行降采样，来获得更多更可靠的样本(Good collection of information is limited, but the amount of data is so big occasion)

本文利用MATLAB 提供的图形图像工具箱里的GU ID E工具,进行简单的心电信号界面的菜单和对话框的设计,使心电信号在记录、处理与诊断方面提供了可视化环境。(MATLAB graphics toolbox GU ID E tools the a simple ECG signal interface design of menus and dialog boxes, the ECG recording, processing and diagnosis provides a visual environment.)

一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，采用（7，4）循环码对信源做信道编码，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，再对信号进行信道解码，画出采用信道编码技术和不采用信道编码技术的误比特率图。(First, this program uses 16QAM modulation mode, for a string of two binary source is modulated, using (7,4) cyclic code of the source-channel coding to do with a raised cosine roll-off function for base-band modulation, and then transferred to a high frequency channel in the channel by adding Gaussian white noise, the use of matched filter demodulation, demodulation constellation plot, using the minimum Euclidean distance decoding decision, and then right channel signals, decoding, channel coding techniques used to draw and non- channel coding techniques using bit error rate plans.)

两种改进的遗传算法（自适应交叉概率的遗传算法，加入领域竞争策略的遗传算法）相比较的matlab程序，基于UCI的两个数据集，可直接运行程序观察效果。(both improved genetic algorithm (adaptive crossover probability of genetic algorithm, to field a competitive strategy of genetic algorithm) compared to the Matlab procedures, the UCI based on two data sets, can run the program directly observe the effect.)
