MATLAB GUI设计学习手记（第二版）源程序 附赠 俄罗斯方块V2.0 本书推荐的学习方法： 1）若您是一个MATLAB初学者，且有充裕的时间来学习GUI设计，您可以从本书的第1章开始循序渐进地学习。 2）若您是一位MATLAB初学者，且时间非常紧迫，建议您先学好第1章，然后依次学习第4章、第5章和第6章，其他章节请根据项目需要有选择性地学习。 3）若您已经掌握了MATLAB的基础语法知识，有一定的MATLAB编程基础，也请浏览一下第1章的内容，尤其是专题分析部分。然后先学习本书第4、5和6章，其他章节请根据项目需要有选择性地学习。 4）若您是一位MATLAB GUI方面的专家或老师，您可以将本书作为一本教学的参考书，本书内容全面、讲解详实、代码精炼，是不可多得的GUI宝典。 (MATLAB GUI design learning Hearts (second edition) source code comes with Tetris V2.0 book recommended learning methods: 1) If you are a MATLAB beginners, and there is plenty of time to learn GUI design from the Chapter 1 of the book began to learn step-by-step. 2) If you are a MATLAB beginners, and the time is very tight, it is recommended that you first learn to Chapter 1, followed by learning Chapter 4, Chapter 5 and Chapter 6, in other sections based on project needs selective learning . 3) If you have mastered the basic grammar of the MATLAB, the MATLAB Programming Fundamentals, please visit the Chapter 1, in particular thematic analysis section. First learning book chapters 4, 5 and 6, then the other chapters selective learning based on project needs. 4) If you are an expert or teacher of a MATLAB GUI, you can book as a teaching reference books, the book is comprehensive, explain the detailed, refined code, is a rare GUI canon.)

基于MATLAB_SIMULINK交流变频调速系统的仿真研究，对spwm交流变频调速进行仿真(spwm)

Solving Engineering Problems Using MATLAB C++ Math Library Introduction In the previous article, we studied how can use MATLAB C API to solve engineering problems. In this article I will show you how can use MATLAB C++ math library. The MATLAB® C++ Math Library serves two separate constituencies: MATLAB programmers seeking more speed or complete independence from interpreted MATLAB, and C++ programmers who need a fast, easy-to-use matrix math library. To each, it offers distinct advantages.

说明：  多逆变器并联，PWM控制下逆变器等效阻抗，诺顿等效电路(Equivalent impedance of inverter)

利用小波进行图像压缩，使用的是一代小波对图像进行的压缩(image compress using wavelet)

在所给定的图片上自动标定出嘴的位置，方便不同图像嘴的定位(In the picture given by the location of automatic calibration of the mouth, mouth to facilitate the positioning of different images)

说明：  VB调用MATLAB 使用VB来调用matlab里的函数，可以综合matlab的强大功能使vb开发的程序效率更高。(MATLAB using VB to call matlab in VB to call the function, can be integrated so that the power of matlab programs vb efficient.)
