Summary: It is decided that a 1st Jacobian matrix (J.M.) cannot be accepted as physically real
unless, for each i, not all aii , aiσ aσi , ... are zero. This is necessary and sufficient that the 2nd J.M. has all main-diagonal
elements non-zero and this is the simplest test for it. It follows that a more correct
form of the relation is ∑1..n[f]ρ=[F], the sum including the n-th power. This last power adds any missing diagonal terms.
