signals and systems basics

使用自相关方法去除信号中的高斯白噪声，提取出目标信号，对做信号处理的十分实用(Using the autocorrelation method to remove Gaussian white noise in the signal, extract the target signal, very practical to do signal processing)

matlabGUI设计的一个简单的例子，实现的图像的阈值的自动调节，然后输出阈值化后的图像，(A simple example matlabGUI designed to automatically adjust the threshold to achieve an image, then the output image after thresholding,)

信号在采集和输送过程中往往会参杂着噪声和干扰，将自适应神经网络与信号处理结合起来，采用最小均方（LSM）算法设计的线性自适应滤波器将信号中的杂波成分滤除。用matlab进行仿真,证实线性自适应滤波器具有良好的滤波功能。(Signal acquisition and delivery process often mingled with the noise and interference, the adaptive neural network combined with signal processing, with a minimum mean square (LSM) linear adaptive filter algorithm designed to signal noise filter components In addition. Using matlab simulation confirms linear adaptive filter has a good filtering.)

用Matlab绘制股市中的蜡烛图（K线图），包含虚拟数据和具体步骤(draw K line in the stock market with Matlab)

在原有matlab程序的基础上增加一个功能即原有程序在未统计之前，一个数默认频次为一，但是这个可以在频次不为1的情况下统计总的频次(Add a function on the basis of the original matlab program that is not before the original program statistics, a number of default frequency is one, but this can count the total frequency in the frequency is not a case)

说明：  细菌觅食算法源代码，可以在MATLAB上运行，调试通过(Bacterial foraging algorithm source code)

基于FFT的图像拼接程序，matlab实现的(Based on the FFT of the image mosaic program, matlab achieved)

该段matlab可实现自由摆系统的演示。(The segment can be realized matlab free pendulum system demonstration.)
