<DIV><SPAN class=370384316-22052009><FONT face=Arial size=2>2Gabriele: I
beleive there is a mistake in your first step. When you start with v_cart =
A*v_cryst, you try to use the property (C*D)' = D' * C', which is true for the
product of two matrices. In our case we have a product of matrix A
and vector v_cryst. So you will get v_cart' = v_cryst' * A</FONT></SPAN></DIV>
