Details:

Dear all,

I get the warning about division by zero if I compute nthroot(0,n) where n is
2 or integer > 3. The problem is in the final correction. The obvious thing it
to do nothing for the elements of x which are zero, but I don't know how to
get this result in a nice way.

Best regards,

Marco
