<acronym id="ukmq4"></acronym> 這是一個模擬第3類模式地震波的matlab腳本。 This a collection of Matlab scripts that solve the antiplane (mode III) earthquake dynamic problem with slip-weakening friction, on a 1D fault embedded in a 2D homogeneous elastic unbounded medium. The problem is formulated as a boundary integral equatiOn and the elastodynamic kernels are analytically derived in the spectral domain (spatial wavenumber). The method is explained e.g. by Morrysey and Geubelle (1997), and has been improved and extensively used by Nadia Lapusta, Alain Cochard, etc.

數值分析算法源碼(java) 這個學期一邊學習java一邊學習數值分析,因此用java寫了一個數值分析算法的軟件包numericalAnalysis. [說明] 適合使用者:會java的,想要學習數值分析算法的人. 本代碼對照書:數值分析第二版,史萬明等編,北京理工大學出版社. 本代碼盡量按書中描述的來寫,可以提供參考. [使用方法] 在java的ide中新建一個項目,把numericalAnalysis包直接拷貝到此項目的源文件夾中,然后要解決什么問題,就相應的編譯運行什么包. 另外有這些類的API提供參考,可以自己根據自己要求寫驅動類.運行API文件夾中的index.html文件就行. [包的結構] numericalAnalysis包中又含有9個包,除function包的是接口外,其余包都含有一個獨立的數值分析問題的類以及其驅動類.9個包如下: differential:微分問題 equatiOn:方程 function:只含一個接口,用來讓用戶寫自己的函數 functionApproximation:離散情況下函數逼近問題 integration:積分問題 interpolation:插值問題 linearequatiOnGroup:線性方程組問題(包括過定方程組) norm:求解向量和矩陣的范數 ode:常微分方程數值解的求解

The main features of the considered identification problem are that there is no an a priori separation of the variables into inputs and outputs and the approximation criterion, called misfit, does not depend on the model representation. The misfit is defined as the minimum of the l2-norm between the given time series and a time series that is consistent with the approximate model. The misfit is equal to zero if and only if the model is exact and the smaller the misfit is (by definition) the more accurate the model is. The considered model class consists of all linear time-invariant systems of bounded complexity and the complexity is specified by the number of inputs and the smallest number of lags in a difference equatiOn representation. We present a Matlab function for approximate identification based on misfit minimization. Although the problem formulation is representation independent, we use input/state/output representations of the system in order

A Matlab toolbox for exact linear time-invariant system identification is presented. The emphasis is on the variety of possible ways to implement the mappings from data to parameters of the data generating system. The considered system representations are input/state/output, difference equatiOn, and left matrix fraction. KEYWORDS: subspace identification, deterministic subspace identification, balanced model reduction, approximate system identification, MPUM.

This is a short text on arrays and pointers in C with an emphasis on using multi-dimensional arrays. The seemingly unrelated C rules are explained as an attempt to unify arrays and pointers, replacing arrays and the basic array equatiOn by a new notation and special rules
