Programing the Finite Element Method withMatlabJack Chessa 3rd October 20021 IntroductionThe goal of this document is to give a very brief overview and directionin the writing of Finite Element code using Matlab . It is assumed that thereader has a basic familiarity with the theory of the Finite Element Method ,and our attention will be mostly on the implementation. An example finiteelement code for analyzing static linear elastic problems written in Matlabis presented to illustrate how to program the Finite Element Method .

This is a matrix of node numbers where each row of the matrix contains the con-nectivity of an element. So if we consider the connectivity matrix elements that describes a mesh of 4-node quadrilaterals the 36th element is de ned
