Select mesh-elements and refine mesh there (via Matlab)

Hi,
i want to select certain mesh-elements and refine the mesh there. It works for domains, but i can not manage to select e.g. certain triangles in a 2d-geometry mesh and refine there.
Here is my code for the domain selection and refinement:
model.mesh('mesh1').feature().create('ref1', 'Refine');
model.mesh('mesh1').feature('ref1').selection().geom('geom_2d', 2).set([1]); % should be a selection of triangles here instead of domains
model.mesh('mesh1').run;

For those who are interested: i finally found out how to do meshing at specific triangles/tetrahedrons.
model.mesh('mesh1').feature().create('ref1', 'Refine');
model.mesh('mesh1').feature('ref1').set('element',[1,3]); % mesh 1st and 3rd triangle
model.mesh('mesh1').run;
In the second line the elements are specified, depending on the underlying geometry these are the array-indices of the triangles or tetrahedrons you would get with e.g.
mesh1.getElem('tri');
model.mesh('mesh1').feature().create('ref1', 'Refine');
model.mesh('mesh1').feature('ref1').set('element',[1,3]); % mesh 1st and 3rd triangle
model.mesh('mesh1').run;
