%% Identify Boundary Labels %% 1 % For example, look at the edge labels for a simple annulus geometry: e1 = [4;0;0;1;.5;0]; % Outside ellipse e2 = [4;0;0;.5;.25;0]; % Inside ellipse ee = [e1 e2]; % Both ellipses lbls = char('outside','inside'); % Ellipse labels lbls = lbls'; % Change to columns sf = 'outside-inside'; % Set formula dl = decsg(ee,sf,lbls); % Geometry now done pdegplot(dl,'EdgeLabels','on')
