此程序用语捷联惯性导航系统中姿态，经度，纬度，速度等参数的计算。(This procedure terminology strapdown inertial navigation system in the posture, longitude, latitude, speed and other parameters of the calculation.)

该matlab程序可以根据所选择的测试库中图片对人脸进行识别，从而在系统中找到与之匹配的图片。(The matlab program can test the library, the selected image on the human face recognition, which is found in the system to match the pictures.)

灰度图转换，可以把彩色图片转换为灰度图片。并进行计算(Grayscale conversion, color images can be converted to gray-scale image. And calculated)

山上有m只猴子要选大王,选举办法如下：所有猴子从1到m进行编号并围坐一圈,从第一号开始按顺序1,2,...n继续报数,凡是报n号的猴子都退出到圈外,照此循环报数,直到圈内只剩下一只猴子时,这只猴子就是大王.输出大王的编号。 (Mountains have m of the monkeys to elect king, method of election are as follows: All monkeys are numbered from 1 to m, and sitting around a circle, to begin from the first order 1,2, ... n continue to report the number of those who reported that n No. The monkeys are out to outsiders the basis of this report the number of cycles until the circle only one monkey, the monkey is king. Output King number.)

这是数学建模的课本上的程序实现，使用matlab实现的(This is a textbook on mathematical modeling program implementation, implementation using matlab)

偏微分方程的matlab解法。文章详细地介绍了数学物理方程的各类解法及其精确度。(Matlab solution of partial differential equations. The article detailed description of the various types of solution of the equations of mathematical physics and its accuracy.)

以某些特殊函数为基将数据过程或数据系列变换为级数系列以发现它的类似频谱的特征，从而实现数据处理。(In certain special functions as the base data process or data series is converted into the series at a similar spectrum to find that it features, in order to achieve data processing.)

文章展示了基于高斯混合模型的语音频谱预测方法。频谱预测可能在传包过程中预防丢包这方面起到大作用。期望最大化算法用两倍或三倍的连续语音因素来测试模型。模型被用来设计第一，儿等指令预测量。预测表用频谱分配状态来估计并和一个简单的参考模型对比。最好的预测表得到一个平均频率扭曲值是0.46dB小于参考模型(This paper presents methods for speech spectrum prediction based on Gaussian mixture models. Spectrum prediction may be useful in a packet transmission system where the sensitivity to packet losses is a major problem. Models of speech are trained by the Expectation Maximization algorithm using pairs, triples etc. of consecutive cepstral vectors. The models are used to design first, second etc. order predictors. The prediction schemes are evaluated using the spectral distortion criterion and compared to a simple reference method. The best prediction scheme obtains an average spectral distortion that is 0.46 dB less than for the reference method. )
