说明：  模拟退火的实现代码，给出具体的案例分析。可以按照不同需要对程序体进行改进(The realization of simulated annealing code, gives specific case studies. According to the different needs of the program to improve body)

使用matlab编程GUI界面模拟琴键，点击GUI按钮发出相应频率的声音(Simulation using matlab programming GUI interface keys, click on the GUI button corresponding frequency sound issue)

将一个512×512的lena.bmp图像进行DCT变换，对得到的DCT系数按8×8块进行分层（分三层），重组填充得到新的系数矩阵，结果发现原图像的能量集中在了新图像的左上角低频部分。(The lena.bmp an image of 512 × 512 is subjected to DCT transform, the DCT coefficients obtained by layering 8 × 8 block (of three), to obtain a new recombinant filling coefficient matrix, the energy of the original image is found concentrated in upper left corner of the low-frequency part of the new image.)

在Juan Cardelino发布的FMM(fast marching methos)2维程序基础上改写的3维程序。并改写成适合复杂速度模型，可用于地震旅行时计算。大模型3d算法在matlab下计算速度较慢，根据源码中的注释很容易改写成c程序。(3D FMM program revised from Juan Cardelino s 2D version. The program can calculate the seismic traveltimes in 3D complex model)

说明：  此书《独立分量分析的原理与应用》是一本非常好的书，适合通信，声纳，地震等等从事这方面研究的技术人员。(The book, &quot Independent Component Analysis Theory and Application&quot is a very good book, for communications, sonar, seismic research in this area and so the technical staff.)

通过simulink图搭建三相逆变器的控制图，采用SVPWM控制技术，是三相逆变器输出电流谐波很小。(Build a three-phase inverter control charts simulink diagram by using SVPWM control technology, is a three-phase inverter output current harmonics is small.)

这是一个matlab的初学者的小算例，非常适合于初学者学习(This is a beginner' s small matlab example is very suitable for beginners to learn)
