Coupling Comsol and MAtlab (?)

I have been modeling chemical processes with Comsol 3.4 and exporting it to Matlab workspace (saving it as a M file). In some situations using the 'femtime' function from Comsol, to numerically integrate the system, leads to an expensive computation time even with reduced mesh size.
COMSOL Multiphysics is equipped with powerful backward difference time integration methods (of order up to 5) with adaptive time step, while its interface with MATLAB permits also the application of explicit time integrators, such as of Runge–Kutta type, whose basic advantage is the low requirements of computational memory, an issue of uttermost critical.
I have hardly tried to implement a Matlab 'odesuite'. But I haven't succeeded. I would like to known
how to perform integration with Matlab 'odesuite' of a Comsol generated problem.
moreover, it is possible to export the right hand side and the Jacobian of a system generate in comsol to a Matlab file?
Thanks
Marcus
