I'm not sure what's meant by earth coordinates -- geodetic latitude, longitude, and height? Or perhaps you're using an earth-centered earth-fixed (ECEF) geocentric Cartesian system? In any case, there are ways to convert among these systems and UTM using the Mapping Toolbox functions mfwdtran, minvtran, geodetic2ecef, and ecef2geodetic, and there's also lla2ecef and ecef2lla in Aerospace Toolbox.
