What Is Optimization Toolbox?

linprogthe primal objective < -1e+10 and the dual objective < 1e+6.The primal appears to be infeasible and the dual unbounded sincethe dual objective > 1e+10 and the primal objective > -1e+6.Both the primal and the dual appear to be infeasible.Note that, for example, the primal (objective) can be unbounded and theprimal residual, which is a measure of primal constraint satisfaction,can be small.Medium-Scale Optimizationlinprog gives a warning when the problem is infeasible.Warning: The constraints are overly stringent;there is no feasible solution.In this case, linprog produces a result that minimizes the worst caseconstraint violation.When the equality constraints are inconsistent, linprog givesWarning: The equality constraints are overlystringent; there is no feasible solution.Unbounded solutions result in the warningWarning: The solution is unbounded and at infinity;the constraints are not restrictive enough.In this case, linprog returns a value of x that satisfies the constraints.LimitationsMedium-Scale OptimizationAt this time, the only levels of display, using the Display option inoptions, are'off' and 'final'; iterative output using 'iter' is notavailable.8-139
