Error in initmesh (line 157) [p,e,t,c]=pderespe(g,p,e,t,c,Hmax,tol,tol2,Hmax,Hgrad);

Error in pdegplot (line 75) hh = plotTwoDGeometry(g, plotEdgeNums, plotSubLabels);

  • When you plot a geometry in shaded mode, the function calls initmesh to generate triangles that can be used to pass to graphics for shading. There is a bug in the pdegplot function that is leading to a failure in the generation of the triangles. Replace line 112 of the pdegplot function with the following:
    [p1,~,t1]=initmesh(g,'init','on', 'MesherVersion','R2013a');
    If that fails to resolve the issue please let me know. This bug will be fixed in the next release.
