這是一個(gè)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.

Introduction Some times it is required that we build a shared library (DLL) from an m-file. M-files are functions that are written in Matlab editor and can be used from Matlab command prompt. In m-files, we employ Matlab built-in functions or toolbox functions to compute something. In my past articles, I showed you some ways to use Matlab engine (vis. API, C++ class or Matlab engine API) for employing Matlab built-in functions, but what about functions that we develop? How can we use them in VC? Is there any interface? This article shows you an idea to employ your own Matlab functions.

matlab生成m序列的函數(shù) 原來(lái)那個(gè)效率太低,主要是因?yàn)閷?shí)際應(yīng)用并不需要生成太長(zhǎng)的m序列,加入了需求長(zhǎng)度,能有效減少運(yùn)行時(shí)間。25級(jí)的移位寄存器,運(yùn)行了一個(gè)小時(shí)都沒(méi)有出來(lái)一周期,我僅僅需要三千bit而已。改進(jìn)版:
