Can linprog give an integer value of x's?

Hi
I have a linprog code that has x1,x2,x3 and x4 in the objective function.
The results I get give me values in the form: x = 6.6667 0.0420 0 0
Which in the case I am trying to model doesn't make physical sense because the x's represent the number of units of a specific technology, and therefore for example 0.0420 doesn't in fact exist. Is there anyway to "force" linprog to find the optimum integer value of x?
Thank you

No there isn't. Integer linear programming is a different beast. Perhaps this one from the file exchange might help:

Alternatively, I'm pretty sure there are matlab bindings available for glpk
