I have assembled Mass and Stiffness matrices with a kind of free element method, but the determinants of my Mass and Stiffness matrices is infinite and zero. I'm completely confused and don't know what to do. Does MATLAB have any features help me overcome this problem?

Does this mean, that the "kind of free element method" you have applied is wrong or that you made a mistake? How could we suggest a solution, when the problem is describe very vaguely only?
