编写的MATLAB混合基4*5程序，运行通过(Written in MATLAB mixed base 4* 5 program, run by)

本程序用三边测量法来计算未知节点坐标且假设用于定位的锚节点位于等边三角形的三个顶点上。(This program uses trilateration to calculate the coordinates of unknown nodes and assume the anchor node for positioning in the equilateral triangle of three vertices.)

相当完整的NUFFT程序代码，注释非常清晰。简单易懂。国外网站上找到的程序，验证过完全正确。 (Fairly complete NUFFT code, comments, very clear. Easy to understand. Found on the website of the program abroad, proven entirely correct.)

用龙贝格法求定积分，此例的变量数为三，但整体思路是没错的。(With Romberg method for the definite integral, the number of variables in this case is three, but the overall idea is correct.)

函数逼近的程序是一元函数的逼近，效果不错(function bijin de chengxu )

角度和时延联合估计（JADE）算法MATLAB程序,适合学习(Joint angle and delay estimation (JADE) algorithm MATLAB program for learning)

说明：  matlab粗糙集属性约简程序，含详细注释(matlab rough set attribute reduction process, with detailed notes)

实现图像的同态滤波，但是在使用之前需要将图片替换成自己的图片，并且要将图片转换成灰度图片(Achieve homomorphic filtering of the image, but need to be replaced before using the pictures into your own picture, and you want to convert the picture into a grayscale picture)
