% Function to set up the initial grid. % % You can replace the mesh by whatever you like (satisfying % the rules set out at the beginning of Section 2.2). Just % edit the function if you want to change the mesh. Use % the function "visualise" to check that you have the mesh % which you want. function [nodes,elements] = initial_mesh nodes = [[0.0 0.0 1];... [1.0 0.0 1];... [1.0 1.0 1];... [0.0 1.0 1]]; % The entry in the third column specifies % whether the node is a boundary node or % an interior one (1=boundary, 0=interior) elements = [[1 2 3 ];... [1 3 4 ]];
