Set the coordinates of nodes via matlab

I'm using Livelink with matlab and I'm trying to define my model using matlab software. Everything for me seems quite clear, except one thing. Firstly I create the geometry using following comands:
geom=model.geom.create('geom',2);
sq=geom.feature.create('sq','Rectangle');
sq.set('size',[80 10]);
geom.run;
Its a 2D model, geometry is a simple rectangle with 80 width and 10 height. Secondly I need to mesh the created geometry. In this case I want to define my own mesh. I calculated the coordinates of the nodes in the mesh:
XYZ =
0 10 20 30 40 50 60 70 80 0 10 20 30 40 50 60 70 80
0 0 0 0 0 0 0 0 0 10 10 10 10 10 10 10 10 10
The structure of this matrix is the same as the structure of vertex for 2D triangular element. Also I calculated a element matrix, with number of nodes:
ELEM =
1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8
2 3 4 5 6 7 8 9 11 12 13 14 15 16 17 18
11 12 13 14 15 16 17 18 10 11 12 13 14 15 16 17
Then I'm trying to create a mesh with these values:
model.mesh().create('mesh', 'geom');
model.mesh('mesh').data().setElem('tri', ELEM-1);
model.mesh('mesh').data().setVertex(XYZ);
model.mesh('mesh').data().createMesh();
But i get an error message:
Geometry and mesh not compatible
Where could be the problem?
