Why Matlab prints incorrect EPS figure

Two same figures are printed via following code, one .EPS and other .PDF.

.PDF is printed as desired (468 point X 468 point or exact 6.5" X 6.5").

.EPS is printed as (472 point x 472 point or 6.55555" X 6.5555").

I know through scaling in PostScript, .EPS can be fitted in the required dimension. But the problem is that MATLAB includes, incorrectly, some white space (about 4 point) on the right side of the .EPS figure. This doesn't happen when the .PDF is generated.
