HHT-realize3

用matlab编写的HUFFMAN树的程序，按照要求输入输入，概率以及信号编号，就可以得到各个信号的Huffman编码。并且有课题报告附上。（编码是逆序输出的，若要改为正序，修改strcat内的两个参数顺序就好）(HUFFMAN prepared using matlab tree program, enter the requested input, probability, and signal numbers, each signal can be Huffman coding.)

MATLAB是美国MathWorks公司出品的商业数学软件，用于算法开发、数据可视化、数据分析以及数值计算的高级技术计算语言和交互式环境，主要包括MATLAB和Simulink两大部分(The MathWorks Inc. MATLAB is a U.S. commercial mathematics software for algorithm development, data visualization, data analysis, and numeric computation senior technical computing language and interactive environment, including MATLAB and Simulink two most)

MATLAB® is a high-level technical computing language and interactive environment for algorithm development, data visualization, data analysis, and numeric computation. Using the MATLAB product, you can solve technical computing problems faster than with traditional programming languages, such as C, C++, and Fortran. You can use MATLAB in a wide range of applications, including signal and image processing, communications, control design, test and measurement, financial modeling and analysis, and computational biology. Add-on toolboxes (collections of special-purpose MATLAB functions, available separately) extend the MATLAB environment to solve particular classes of problems in these application areas. MATLAB provides a number of features for documenting and sharing your work. You can integrate your MATLAB code with other languages and applications, and distribute your MATLAB algorithms and applications.
