fmincon starting value is not x0

Hello. When I call fmincon, I provide a starting point x0. However when I check the value of x at the first iteration it does not start at x0. Is there any way to force fmincon to start precisely at x0? Thanks.

Ok, it was because I provided an x0 point that was equal to the one of the bounds, so matlab treated as outside the bounds and changed the starting value without warning me.
