利用matlab实现数字图像HUFFMAN二元和三元编码，效果不错。(HUFFMAN digital images using matlab binary and ternary coding, good results.)

说明：  这是《matlab小波分析》第四章例子的源代码！(This is the &quot matlab wavelet analysis,&quot Chapter IV of the source code examples!)

MATLAB PPT及实例M文件，主要是基于MATLAB 的数值计算，希望对你有用(MATLAB PPT and examples of M documents, mainly based on MATLAB numerical calculation, hope useful to you)

The codes included here require Matlab platform 7.0.0 or higher. The source codes have been written by the students who have undergone this subject. The codes are problem specific and not general. The principle aim was to develop softwares for illustration of computational methods and are generally far from optimal. Knowledge of any computer language is sufficient to change the parameters in the codes. A person well versed in Matlab should be able to modify these codes or write their own. It is a common knowledge that understanding the codes written by others is not a pleasant experience. Therefore, useful comments have been added in the codes to help users.(The codes included here require Matlab platform 7.0.0 or higher.

粒子群算法在无功优化中的应用，非常简洁，实用(Application of particle swarm optimization in reactive power optimization)

awackley测试函数，经过实验的确可以用，哈哈，分享给大家(awackleytest function, indeed can be used through the experiment, ha ha, for everyone to share)

一次完成最小二乘法辨识系统程序,可以仿真(A complete system parameter identification program that can emulate)

扩展卡尔曼滤波的MATLAB程序，也许有人能用的到。(Extended kalman filter MATLAB, maybe someone can arrive.)

说明：  退火算法程序，经典优化算法，可以找到全局较好的点。(Annealing process, the classical optimization algorithm, can find a good point overall.)
