4 Fourth Step: Minimizing the Functional Using the finite element approximation, the functional W is now a function of the N unknown nodal values ui W = W(u1 , u2 , . . 35) [U]p where the subscripts f and p refer to free and prescribed nodal values, respectively. 36) where the superscript t denote the transpose operator. 37) The final square coefficient matrix is of order Nf , being Nf the number of degree of freedom of the problem. 37) can be written even though the global numbering scheme does not abide to the restriction of numbering the nodes with prescribed potential last.

Dodelaunay,dorenum,period) Besides filename, which obviously is a string containing the name of the geometry description file, the other parameters are flags handling options allowing visualization and mesh optimization as described in the following sections. Flag descriptions are contained in the code and can be visualized with help Mesh Code MeshGUI opens a Matlab dialog where all these options are presented graphically and can be set interactively in a more intuitive way. Please note that Matlab is case sensitive and has a built-in mesh function handling two-dimensional graphs.
