Maltlab DAQ example code

实现在通信系统中眼图的算法，方便观察眼图，以判断其码间串扰(Eye pattern)

MATLAB文件,关于心电信号的采集和处理，不是很全面，谢谢(MATLAB documentation on ECG acquisition and processing, is not very comprehensive, thank you)

in this file is distributed system in two case

设计一CQMFB，低通滤波器H_0 (z)来自一半带滤波器。该半带滤波器的长度为47，通带截止频率ω_p=0.42π，试给出H_0 (z)，H_1 (z)，G_0 (z)，G_1 (z)的幅频响应，单位抽样响应并画图。试着产生一信号，它由两个正弦加白噪声组成，一个在低频，一个在高频，正弦的频率及和白噪声的信噪比自己给定。试用所设计的滤波器组对该信号进行分解和重建。比较重建后的效果，并对结果继续进行分析。(Design a CQMFB, low pass filter H_0 (z) the half-band filter. The length of the half-band filter 47, passband cutoff frequency ω_p = 0.42π, try to give H_0 (z), H_1 (z), G_0 (z), G_1 (z) of the amplitude-frequency response, the unit sample response and Paint. Try to generate a signal that consists of two sinusoidal composition plus white noise, a low frequency, a high frequency in the signal to noise ratio, frequency and sine and white noise of its own given. Trial designed filter group that signal decomposition and reconstruction. Results were rebuilt, and the results continue to be analyzed.)

有关于图像的区域处理的MATLAB软件,已经上机运行过,对MATLAB编程非常有用(Area on the image processing MATLAB software has been running on the machine before, is very useful for MATLAB programming)

遗传算法的GA主函数，选择函数，排序函数，交叉函数，变异函数等等(Genetic algorithm is proposed to GA Lord function, choose function, sort function, crossover function, variation functions and so on )
