信号源个数估计方法

说明：  模拟退火算法事例，用以结果旅行商问题，采用简单的C语言完成，求相对最优的智能算法(This routine is created for solving TSP problem,using simple C language,find the best way to solve optimal problem.)

包括贪吃蛇，俄罗斯方块，扫雷，推箱子，连连看，拼图六款小游戏代码(Including the Snake, the Russian box, mine clearance, Sokoban, Lianliankan, six puzzle game code)

通过在1-10000中随机选取一个整数，让玩家猜测。猜测中会提示玩家，所猜的数字偏大或偏小。(By selecting an integer randomly in 1-10000, let the player guess. In guessing, the player will be prompted. The number of guesses is larger or smaller.)

说明：  Doan in document with Matlab Code

三相交错双向DCDC MATLAB 模型仿真(Three-phase staggered two-way DCDC MATLAB simulation)

说明：  二维傅立叶变换的Matlab实现，是利用图像处理软件对给出的图像进行傅立叶变换处理。在Matlab中，函数fft2表示二维傅立叶变换，函数ifft2则表示二维傅立叶反变换。(The Fourier transform of the image)

用中点画圆法画椭圆。可以改变大小和位置。(Ellipse midpoint drawcircle.You can change the size and position.)

matlab初学者，零基础，简单曲线练手，求指教(Matlab beginners, zero basis, simple curve training, ask for advice.)
