编程实现龙格--库塔方法，并与精确解比较(compare runge--kuta)

超宽带测距中，选目的节点和参考节点。输入节点数量为N和希望的参考节点数量为K，函数返回一个表示目的的节点的整数Nx和一个K维的包括了参考节点ID号的矢量Ref。(Ultra-Wideband Ranging choose destination node and reference nodes. The number of input nodes for N and hope the number of reference node K, the purpose of function that returns a whole number of nodes Nx and including a K-dimensional reference vector of node ID No. Ref.)

均值滤波：把每个像素周围的8个像素来做均值操作，可以平滑图像，速度快，算法简单，但是无法去掉噪声，只能微弱的减弱它。(The mean filtering: 8 pixels around each pixel do mean, you can smooth image, fast and simple algorithm, but can not get rid of the noise, only faint weakened it.)

matlab图形应用篇,三角函数曲线,图形的叠加双y轴图形的绘制,单个轴窗口显示多个图形等32个程序(matlab graphics applications articles, trigonometric curves, the superposition of two-y-axis graph drawing, a single axis of the window display multiple graphics programs such as 32)

说明：  自己写的算术编码的matlab程序,内容是把自己的名字(当然也可以是其他的文字)用算术编码编码后再解码,有详细注释.给初学编码的朋友一些参考.谢谢.(Write matlab arithmetic coding procedure is to divide his name (of course also be other text) and then decode encoded using arithmetic coding, a detailed comment. Beginners encoding a friend to some reference. Thank you.)

matlab教程，非常全面实用。很适合初学者(matlab tutorial is very comprehensive and practical. It is suitable for beginners)

该仿真程序通过窗函数法设计非线性调频信号，并仿真了非线性调频信号的脉冲压缩(this matlab program has simulated the non-linear frequency modulation signal and it s compression)
