This creates a trapezoid wave, similar to the built-in square function but with no duty cycle option

point multiplication of elliptic curve over galois field

一个ldpc码的寻找围长（girth）为10的程序(Ldpc code to find a girth (girth) of the program 10)

说明：  利用Matlab可视化编程设计一个界面，实现对几种常见分布的随机抽样并进行曲线拟合，最后用图像直观地表现出来(Using Matlab to design a visual programming interface, to achieve some common distribution of random sampling and curve fitting, and finally with the image shown visually)

matlab的基本用法,对初学者有用,是必备的基础知识.(Matlab the basic usage, useful for beginners, is an essential knowledge base.)

vectarrow(p0,p1) plots a line vector with arrow pointing from point p0 to point p1. The function can plot both 2D and 3D vector with arrow depending on the dimension of the input

说明：  matlab图像处理：color axis例程(matlab image processing: color axis routines)

用得最多的是最近邻，此处上传的是K-近邻，即k＝1。matlab环境下的代码。附有实例。(used most often is the nearest neighbor, here is uploaded K-neighbor, k = 1. Matlab environment code. With examples.)

该程序能够通过使用Allan方差算法来分析陀螺噪声。(The program can be through the use of Allan variance algorithm to analyze the gyro noise.)
