Stop a long running MATLAB method from within a .NET application

A coworker has developed and compiled several METLAB methods into a .NET DLL that I am referencing from my .NET WinForms application.

Under some cercumstances that MATLAB method that I call does not terminate - it just runs forever. My application can detect when the method is taking too long to return. Is there an appropriate way to stop it from within the .NET application?

THanks
