I am working with a large integer programming problem, which may take huge amount of time to complete the program. I would only like to get some feasible integer point in the constraint set rather than solving the optimization problem. Is there options in intlinprog can achieve this?

Sure, you are free to use the built-in 'savemilpsolutions' output function to collect the solutions, and eiither give a random or no objective function vector. I believe that giving a random objective function vector can, in some cases, help the solver, but you are free to leave the objective out entirely if you like. See the documentation for the f argument.
