Abstract:
1. A machine executed method to evaluate a metacomplex interval expression to return a metacomplex interval that includes all image points of the evaluation, comprising: (A) specifying, by an interval evaluator in a machine, an evaluation sequence of interval operators, interval operands, and postimage intervals, for the interval expression, including branchcut criteria for said interval operands which require auxiliary branchcut information, (B) selecting at least one interval operator from an interval operator pool in the machine, wherein the at least one interval operator is selected from a group consisting of: (C) numerically evaluating, by an interval evaluator in the machine, said predetermined metacomplex interval expression, by iterating through the interval operators of the evaluation sequence and applying corresponding interval operators from the interval operator pool using the interval operator selection, (D) returning the interval result from the numerical evaluation that includes all possible point evaluation results of the evaluation of the interval expression.
