本程序画出了时间序列下的各变量变化图，得到混沌性质，从而在区域内对变量进行取值，达到模拟出混沌的目的(This procedure draws the time series of each variable changes in plans, the chaotic nature, and thus in the region of variable values, to simulate the purpose of Chaos)

应用独立分量分析方法对图片进行图像分离处理，可以将医学影像的图片进行分离，单独进行分析。(Independent component analysis of images for image separation processing, medical imaging picture can be separated, analyzed separately.)

时间序列建模AR（1）后的卡尔曼滤波程序，整个过程非常详细，里面自带一组数据。(Time series modeling AR (1) after the Kalman filtering process, the entire process is very detailed, which comes with a set of data.)

FIR(Finite Impulse Response)滤波器：有限长单位冲激响应滤波器，是数字信号处理系统中最基本的元件，它可以在保证任意幅频特性的同时具有严格的线性相频特性，同时其单位抽样响应是有限长的，因而滤波器是稳定的系统。因此，FIR滤波器在通信、图像处理、模式识别等领域都有着广泛的应用。 (FIR (Finite Impulse Response) filters: finite impulse response filter unit, digital signal processing system is the most basic components, it can ensure that any increase in the frequency characteristics of both a strictly linear phase frequency characteristics, while its unit sample response is finite, and therefore the system filter is stable. Therefore, FIR filters in communications, image processing, pattern recognition and other fields have a wide range of applications.)

1.产生正弦信号，方波信号，均匀噪声； 2.信号的叠加； 3.信号的相关分析； 4.信号的卷积； 5.信号的和； 6.信号的频谱图。(1. Generate sine signal, square wave signals, uniform noise 2. Signal superposition 3. The signal correlation analysis 4. The convolution of signal 5. The sum of signal 6. The signal spectrum.)

这个是霍夫曼编码的问题，要求输入只含有ABCD的四句话，且每句8个字符的长度，然后求出四个字符每个的概率，然后当成权值计算霍夫曼编码，我的这个程序已经实现了输入、概率统计、计算出霍夫曼编码存在了bian[]这个数组中(hoffuman decoding)

matlab编写的串口调试工具，数据接收部分采用中断方式，保证了实时的数据显示 。在获取端口部分采用了try catch 的方式，可以更加方便的选取端口。(this is a simple serial tool scripted by matlab. I used interrupt to ensure the instant display of received data.)
