Two real valued functions ƒ and

*g*are orthogonal relative to a weight function σ on an interval if the integral over the interval of ƒ·*g*·σ vanishes.A function defined on the edges of a network or the arcs of a directed network, whose value at each edge or arc is the unique nonnegative integer assigned to that edge or arc.
