What Is Optimization Toolbox?

linproglambdaoutput-2 No feasible point was found.-3 Problem is unbounded.-4 NaN value was encountered duringexecution of the algorithm.-5 Both primal and dual problemsare infeasible.-7 Search direction became too small.No further progress could be made.Structure containing the Lagrange multipliers atthe solution x (separated by constraint type).

The fields of the structure are:algorithmcgiterationsiterationsmessageAlgorithm usedThe number of conjugate gradientiterations (large-scale algorithmonly).Number of iterationsExit messageOptionsOptimization options used by linprog. Some options apply to allalgorithms, and others are only relevant when using the large-scalealgorithm.You can use optimset to set or change the values of thesefields in the options structure, options.
