Often for loops can be eliminated using Matlabs vectorized addressing. 12.3 FEM Discretization 186. 12.4 Viscoelastoplasticity 188. 12.5 Matlab Implementation 190.

for loop, especially nested for loops since these can make a Matlab programs run time orders of magnitude longer than may be needed. Often for loops can be eliminated using Matlab’s vectorized addressing. For example, the following Matlab code which sets the row and column of a matrix Ato zero and puts one on the diagonal for i=1:size(A,2) A(n,i)=0; end PROGRAMMING OF FINITE ELEMENT METHODS IN MATLAB LONG CHEN We shall discuss how to implement the linear ﬁnite element method for solving the Pois-son equation. We begin with the data structure to represent the triangulation and boundary conditions, introduce the sparse matrix, and then discuss the assembling process. Since we Programming of Finite Element Methods in MATLAB @article{Chen2018ProgrammingOF, title={Programming of Finite Element Methods in MATLAB}, author={Long Chen}, journal={arXiv: Numerical Analysis}, year={2018} } Long Chen; Published 2018; Computer Science, Mathematics; arXiv: Numerical Analysis Finite Element Analysis Using MATLAB Toolbox I n this section, a MATLAB3 toolbox CALFEM4 is introduced.
