图书交点间断Galerkin方法：算法、分析与应用中的matlab源程序，包括一维、二维和三维的一些算例。交点间断Galerkin方法相比传统的有限差分法和有限体积法，可提供更精确的数值求解，在流体力学的数值计算有着广泛的应用。(The source code of Intersection Discontinuous Galerkin Method: Algorithms, Analysis and Applications includes one-dimensional, two-dimensional and three-dimensional examples. Intersection discontinuous Galerkin method can provide more accurate numerical solution than the traditional finite difference method and finite volume method. It is widely used in the numerical calculation of fluid mechanics.)

一种噪声辅助数据分析方法,包括主成分分析、因子分析、贝叶斯分析，小波包分析提取振动信号中的特征频率。( A noise auxiliary data analysis method, Including principal component analysis, factor analysis, Bayesian analysis, Wavelet packet analysis to extract vibration signal characteristic frequency.)

小波分解可以使人们在任意尺度观察信号，只需所采用的小波函数的尺度合适。小波分解将信号分解为近似分量和细节分量，它们在应用中分别有不同的特点。比如，对含有噪声的信号，噪声分量的主要能量集中在小波分解的细节分量中，对细节分量做进一步处理，比如阈值处理，可以过滤噪声。(Wavelet decomposition allows people to observe signals at any scale, just the size of the wavelet function is appropriate. The wavelet decomposition decomposes the signal into approximate and detail components, and they have different characteristics in application. For example, for noisy signals, the main energy of the noise component is concentrated in the detail components of wavelet decomposition, and further processing the detail components, such as threshold processing, can filter the noise.)
