This procedure is specific for systems of distance equations (see section 3.3.2.1) for determining an initial search domain. It may determine either determine an initial guess for the input intervals or to improve a given initial guess.

The syntax is:

Bound_Distance(Func,Var,Result)where

An optional fourth argument of this procedure is an initial guess for the search domain. The procedure will return:

- -1: there is no solution to the system of equations
- 0: the procedure has not been able to find an initial search domain or to improve the initial guess
- 1: the procedure has been able to determine an initial guess or to improve the initial guess
