... recall that the mignitude of x is defined as mig (x) =  min (|x |, |x|) if 0 /∈ x 0 otherwise. An implementation written in INTLAB of interval Gaussian elimination with mignitude pivoting is given by ... d i = (A −1 ) ii , and α i = A ii  − 1/d i , β i = u i /d i − |b i |. Then Σ(A, b) is contained in the vector x with components x i = b i + [−β i , β i ] A ii + [−...
