说明：  Matlab网格划分程序可以将结构的四边形网格转换为三角形网格。 但该文件中内容重复了mesh2tri函数写了两遍，可以删除重复部分。 Demo: clear all close all clc (Matlab grid program 1. Create mesh grid 2. Plot the original rectangular mesh 3.1 forward slash division of quadrilateral)

与Field_II配套使用，提供了一个基于matlab平台的gui界面，可自由定制参数，选择成像方式，功能强大。(This tutorial is designed to give you an introduction to Field_II, an acoustic pressure field simulation package written by Dr. Joergen Jensen. is the method for you. To run this tutorial, you will need to have MATLAB available on your computer. Download the Field_II source code and the Field_II_GUI files to your machine,and then run through the tutorial.)

基于高频电流注入的永磁同步电机初始角检测，具体是旋变高频电流注入。效果不错，外带相关论文几篇，很有参考意义。(The initial angle detection based on high frequency current injection of permanent magnet synchronous motor, in particular high-frequency current injection resolver. Well, take away a few relevant papers, it is very useful.)

说明：  解决基追踪降噪(Basis Pursuit De-Noising, BPDN)问题(Solve the problem of base pursuit de noising (bpdn))

数据分析(Python language learning data analysis)

特别经典的俄罗斯方块matlab程序！图形不错，界面也做得很好，共享给大家一起学习！(In particular the classic Tetris matlab program! Good graphics, the interface they have done well to share for everyone to learn!)

说明：  walshl变换的定义的原代码（m）及说明文件（txt）。(the instruction(.txt) and defination(.m) of walsh transform )

tangent bug is usefull for use it

一个是用matlab实现指纹识别程序。里面附带指纹图片，并用其作为例子实现指纹图像的匹配。(One is to use matlab to achieve fingerprint identification procedure. Which comes with the fingerprint image, and use it as an example to achieve the matching fingerprint images.)

高斯法的动力学建模，一个旋转体加偏心摆的简单模型 mdl文件是主程序(Gauss law dynamics modeling, plus a rotating body placed eccentric mdl file is a simple model of the main program)
