利用有限差分法 (Finite Differential Method, FDM)将场域离散为许多小网格，应用差分原理，将求解连续函数的泊松方程问题转换为求解网格节点上的差分方程组的问题。(The use of finite difference method (Finite Differential Method, FDM) will field for many small discrete grid, the application of differential principle, the continuous function for solving Poisson' s equation for solving the problem is converted to grid nodes on the issue of differential equations.)

回归分析中，检验自变量的重要性，将变量一个一个引入引入变量的条件是其偏回归平方和经检验时显著的，在引入新变量的同时，对已入选的变量逐个检验，将不显著的变量剔除。(The importance of the independent variables of regression analysis, test, introducing variable is introduced one by one into the condition of variable is the partial regression sum of squares in significantly after inspection, and at the same time of introducing new variables, for the selected variables one by one test, will not be significant variables.)

测量的磁滞回线数据使用matlab拟合的方法(The measured hysteresis loop data is matlab-fitted)

频域的模态参数识别方法之一，可以对振动信号进行分析处理，得出结构的固有频率，阻尼比，振型系数，方法很好，程序完整(One of modal parameter identification method in the frequency domain, can the vibration signal analysis and processing, obtain the natural frequencies, damping ratio, mode shape coefficient method is very good, complete procedures)

这个例子是书上的Morlet小波程序，运行时总是出错。包括 ??? Error using ==> CWT_Morlet at 11 At least 1 parameter required! 这个问题是怎么回事？error的用法错在哪里了？还有，这个程序还有哪些错误呢？比如函数定义之类的问题？请各位大侠帮帮我吧。( Review the release notes for other MathWorks® products required for this product (for example, MATLAB® or Simulink® ).
