格式：[huffcodes，氢，領 ，电子] = huffmancoding（磷，氮） ％输入：p是每个字母符号的概率 （如：对= [0.3 0.2 0.2 0.2 .06 .04]） n是一个整数，决定在每个帧的符号数量 （默认：n = 1时） ％输出：huffcodes：huffmancodes 答：源熵 甲肝：平均熵编码 电子邮件：科丁效率(format : [huffcodes,H,Hav,e]=huffmancoding(p,n) inputs: p is the probability of each alphabet symbol ( eg:p=[.3 .2 .2 .2 .06 .04] ) n is an integer that determines number of symbols at each frame (default:n=1) outputs: huffcodes: huffmancodes H: source entropy Hav: average entropy for coding e: codding efficiency )

system design for plate recognation

1、设计一个62阶低通滤波器，采样频率为9kHz，通带截止频率为3kHz，要求阻带最小衰减50dB。 2、将滤波器系数输出到txt文本文档。 (1, the design of a 62-order low-pass filter, the sampling frequency is 9kHz, passband cutoff frequency of 3kHz, requires a minimum stopband attenuation 50dB. 2, the output of the filter coefficients to txt documents.)

说明：  基于小波变换的图像分解与重构，实验效果明显，在matlab中实现(Based on wavelet transform image decomposition and reconstruction of the experimental effect, in Matlab)

电力系统200KW太阳能电池接电力系统, matlab图解. 我同时分享了另一个300kw系统图，两者区别在于控制系统，可以对比一下。 (200-kW Grid-Connected PV Array (Average Model))

Newmark -β法原理Newmark-法是一种逐步积分的方法，避免了任何叠加的应用，能很好的适应非 线性的反应分析。 (Newmark-β law principle Newmark- method is a gradual integration of the ways to avoid any superposition of application, can be well adapted to nonlinear response analysis.)

PSO,A GOOD SOURCE IN MATLAB FROM IEEE.

国外的一个用C实现的类似matlab数学库，功能貌似很强大，很多功能已经有源码了，喜欢C语言的人有福了。(Foreign matlab math library in C, the function looks like a very powerful, many functions have been source of the Blessed are those who like the C language.)

音乐闹钟不但定时播放音乐而且有好的界面设计(the musicclock is used to remind of you the important thing and it has a good appearance.)

多尺度Retinex代码算法，能够很好的是实现边缘锐化和对比度增强。(Multi scale Retinex code algorithm, can very good realize edge sharpening and contrast enhancement.)
