This folder or any similar folder such as this created to hold your speech files, should be copied into the root folder C: , created on the local hard drive. Then the path will read thus C:SpeechDataTope... etc. An alternative is to modify the file setTemplates.m to change the directory as appropriate. Try to use the same microphone for training as well as for recognition to obtain improved accuracy. You might also need to tweak your sound card s mic input level. The recognition time is dependent on systems s processing power and has been observed at between 1 and 5 seconds on various x86 platforms. To speed up recognition, you can implement unconstrained DTW (this is the code portion taking most time).

在matlab平台上对线极化、圆极化、椭圆极化电磁波的电场和磁场的情况进行仿真(On the platform of the situation matlab linear polarization, circular polarization, elliptical polarization of electromagnetic waves and magnetic field simulation)

在matlab中实现文本、音频、图片、视频的隐写和恢复(Implement the text, audio, picture, and video steganography)

这是解决图论中最小树问题的求解程序，是一种很好的解决方法(This is to solve minimum spanning tree in graph theory problem solving process, is a good solution)

给出了信号压缩通常的变换-量化-编码函数。DHT函数为离散DHT变换，是FFT变换的近似，其正反变换相同，克服了FFT复系数不利于存储的缺点。LLMAX函数给出了某x序列在固定比特下的最佳量化输出。熵编码函数为霍夫曼编码。(Gives the signal compression usually transform- quantitative- coding function. DHT DHT discrete transform function, the FFT transform approximation, the same positive and negative transformation, overcoming complex FFT coefficient is not conducive to storage shortcomings. LLMAX function x is given a fixed bit sequence in the optimum quantized output. Entropy coding function as Huffman coding.)

一个二维静电场，电位函数为φ（x, y），将正方形分成25个正方形网格。有16个内部网格点。假定16个网格点的初值都定为零，试用超松弛法确定16个内部网格点的电位值。(A two dimensional electrostatic field, the potential function for phi (x, y), the square into 25 square grid. There are 16 internal grid point. Assume that 16 mesh point of initial value at zero, trial overrelaxation method to determine the potential value of 16 internal grid point.)

这部分代码主要实现了TURBO码的编解码，运用max-log-map译码方法进行译码(this code realise the encode and decode function of turbo,the decoding algorithm is by max-log-map)
