数字图像处理（matlab版）小波变换程序(wavelet)

该程序演示了三角函数和双曲函数以及对数函数之间的关系，可供数学学习研究之用。 (The program demonstrates the trigonometric and hyperbolic functions and the relationship between the logarithmic functions are available for mathematics learning research.)

说明：  电力系统潮流的计算机辅助分析 本课题要求对一14节点的电力系统分别使用MATLAB和PSASP软件进行潮流计算及分析，其具体要求如下： 1）用MATLAB实现对该系统的潮流计算。需要MATLAB语言编制程序形成节点导纳矩阵、形成雅克比矩阵、用高斯消去法解修正方程式，并编写输出程序用以输出节点导纳矩阵、节点电压（包括电压的相角和幅值）、以及各支路的首端功率、末端功率和功率损耗，然后调式并在MATLAB运行环境下运行程序输出结果，再将结果制成表格。(Computer Aided Analysis of Power Flow)

egion growing approach is the opposite of the split and merge approach: An initial set of small areas are iteratively merged according to similarity constraints. Start by choosing an arbitrary seed pixel and compare it with neighbouring pixels. Region is grown from the seed pixel by adding in neighbouring pixels that are similar, increasing the size of the region. When the growth of one region stops we simply choose another seed pixel which does not yet belong to any region and start again.

说明：  可以方便的计算混沌系统的李雅普诺诺夫指数，只要改变其动力方程即可。(Chaotic system can easily calculate the lyapunov exponent, as long as you change the power equation)

说明：  MATLAB编程(第二版)是老师强烈推荐的，这个电子版是找了好久才找到的，很清晰，有目录。(MATLAB Programming (Second Edition) is the teacher strongly recommended that this electronic version is looking for a long time to find, very clear, there are directories.)
