代理模式02

说明：  以悬臂梁为例，用有限元法编程生成质量矩阵和刚度矩阵（采用平面梁单元，单元数在10到30之间）。 使用matlab的用于广义特征值问题分析的函数（eig(A,B,'chol')，该命令使用乔莱斯基分解的方法，计算对称矩阵A和对称正定矩阵B的广义特征值问题。A对应刚度矩阵，B对应质量矩阵）计算梁的前三阶固有频率和振型，计算得到梁的前三阶固有频率和振型，并画出振型图。(Taking cantilever beam as an example, the mass matrix and stiffness matrix are programmed by finite element method (using planar beam elements, with units ranging from 10 to 30). Using Matlab's function (eig (A, B,'chol') for the generalized eigenvalue problem analysis, the command uses the Jo Lessky decomposition method to calculate the generalized eigenvalue problem of the symmetric matrix A and the symmetric positive definite matrix B. A corresponds to the stiffness matrix and B corresponding to the mass matrix. The first three natural frequencies and modes of the beam are calculated, and the first three natural frequencies and modes of the beams are calculated, and the vibration pattern is drawn.)

Cats是一个使用最大似然估计来使用多参数的时间序列（比如：连续的GPS）。该程序同时估计所有参数，但是分两部分来估计速度，线性部分包括一个offset and slope，突变（as form earthquakes）、正弦部分（包括年周期和半年周期），而非线性负分包括几个不同的噪声模型及其组合。(Cats is a time series (e.g., continuous GPS) using multiple parameters using maximum likelihood estimation. The procedure to estimate all parameters simultaneously, but is divided into two parts to estimate the speed of the linear part includes a offset and slope (as form earthquakes), mutation, sinusoidal components (including annual and semiannual period), and the nonlinear negative consists of different noise models and their combination.)
