sorry this was correct, somehow the vectors have the same value, but I still do not understand why the error is invalidating the subtraction.

 v = [0,0;0,0;0,0]

v =

   0   0

   0   0

   0   0

>> x-v

ans =

   1   0

   1   1

   2   4

>> x

x =

   1   0

   1   1

   2   4

What do you mean invalidating the subtraction?  since v is a zero matrix, x-v=x.  there should be no change to x....
