KKT conditions

Hi all,

Does anyone know if fmincon calculates the KKT condition
differently from the published formula? The reason I ask is
that I calculated the KKT for a problem I am working on to
be 8.57e-5, but the first-order optimality display at the
end of the run shows 8.57e-3--same numbers, two order of
magnitude difference.

Could it be my calculation is wrong, or does Matlab use an
approximation for the KKT that might yield a different answer?
