COMSOL Mutiphysics and External MATLAB function

Dear All,

I am using COMSOL Multiphysics(version 5.2) for solving the models(time dependent) which calls external MATLAB functions. The objective of external MATLAB functions is to resolve ODE and give a return value to COMSOL.

I would like to know how I can solve ODE externally through MATLAB for the COMSOL model?

Thanks,
Krushna
