说明：  这是matlab编写的射线网格法追踪，用于追踪波的射线轨迹(This is prepared matlab ray tracing grid method, used to track wave ray tracing)

给一段1s声音，添加入噪声，输出，然后去除噪声，输出(add noise to a 1s-length voice,excute it ,and remove the noise,and excute it)

本程序是通过对gps全球定位系统的卡尔曼滤波，获得较为准确的结果。(This program is through the GPS system, Kalman filtering, to obtain more accurate results.)

此程序能在MATLAB上实现低通滤波器，功能很强大(That this procedure can in MATLAB to achieve low-pass filter, a very powerful feature)

该代码为PCA主成分分析，可用于特征选择，选取贡献最大的前三个主成分(The code for the PCA principal component analysis, can be used for feature selection, select the largest contribution to the first three principal components)

用减谱法进行语音增强，效果还不错。 读入语音，调整噪声水平即可。(Spectral method used by speech enhancement, the effect was not bad. Read into the voice, the noise level can be adjusted.)

说明：  变质量刚体模型的6自由度运动matlab仿真程序(Variable mass rigid-body model of 6-DOF movement matlab simulation program)

说明：  该程序运行多次，并输出合法解及其图形输出的图形，图形是在正常情况下的(Run the program several times, and output a legitimate solution and its graphics output graphics, graphics in the normal circumstances of)

各种方程的解法，包括代数方程，线性方程组，线性微分方程等等。。(Solution of various equations, including algebraic equations, linear equations, linear differential equations and so on. .)

根据地震记录的统计特征和相应假设，本文采用 ARMA 模型描述地震子波，基于 高阶累积量的 ARMA 模型地震子波提取方法不仅可在压制高斯色噪声的同时保留所需 地震信号的相位信息(For the cumulant based ARMA (autoregressive moving average ) model seismic wavelet extraction method could not only retain the pahse information of the seismic wavlet while eliminating the colored Gaussian noise, but also provide a parsimonious, more efficient )
