可对.txt文本进行霍夫曼编码，并计算其压缩率(Can. Txt text Huffman code, and calculate the compression ratio)

Included are the files wav1.m, wav2.m, wavecoef.mat and readme. wav2 function implements the tree structured wavelet transform of the input matrix, up to the given level of decomposition. Wav2 uses another function called wav1, which takes the well known wavelet transform of the given matrix. Daubechies wavelet coefficients are used for wavelet transform operation wahich is saved in wavcoeff.mat. (Included are the files wav1.m, wav2.m. wavecoef.mat and readme. wav2 function biennium max the tree structured wavelet transform of t he input matrix. given up to the level of decomposition. Wav2 use s wav1 another function called, which takes the well known wavelet transform of the given matrix. Daubechies wavelet coeffici separations are used for wavelet transform operation w ahich is saved in wavcoeff.mat.)

基于matlab的标准ieee的14节点系统，运行正常。(standard IEEE fourteen node system based on matlab simulink, itis operating normally.)

飞机仿真软件包dubsi10-2，可以与FDC tool（本站已有）一起使用的matlab/simulink仿真软件，主要对飞机的滚转姿态控制进行仿真研究，内有丰富的案例。(The Dutchroll Blockset for Simulink, DUBSI, is a stand-alone version of the blocklibrary BLOCKLIB_MISC in version 2.0 (or later) of the Flight Dynamics and Control (FDC) Toolbox, which is currently under development. It contains a number of general-purpose Simulink blocks, which can be used for more applications than flight dynamics research only. Both the FDC toolbox and the DUBSI blockset are copyrighted by M.O. Rauw see COPYING.TXT for more details. )
