What can I change on the quickersim routine (see attached importMeshGmsh.m) so that I can import a gmsh file (see attached reactor2.gmsh file) into matlab.
When I try, I get the "index exceeds matrix dimensions" error.
The error is in importMeshGmsh (line 114) p(1:3,i) = [abcd(2:4)]';
Regards

I also got this error message and found by deleting the text between $physicalnames and $EndPhysicalNames, this error message goes away. However, I then encountered a NEW error as follows:
Error using ==
Matrix dimensions must agree.
Error in importMeshGmsh (line 202)
if(sum(t([1 2],el)'==[n1 n2])~=2 && sum(t([2 3],el)'==[n1 n2])~=2 && sum(t([3
1],el)'==[n1 n2])~=2)
Error in ID_Pen (line 7)
[p,e,t] = importMeshGmsh('taper_1.msh');
One thing I noticed is that in the tutorial files, the number of elements is precisely double the number of nodes, whereas in my own msh file, they are the same...!
Can anyone help me fix this ?

As the original importMeshGmsh is no longer attached, this question would appear to relate to the Gmsh toolbox, http://gmsh.info/doc/texinfo/gmsh.html . However, we would probably need to know which version of the code you are using, and an example file would help.
