What Is Optimization Toolbox?

lsqlinDiagnosticsLarge-Scale OptimizationThe large-scale method does not allow equal upper and lower bounds.For example, if lb(2) == ub(2), thenlsqlin gives the following error:Equal upper and lower bounds not permittedin this large-scale method.Use equality constraints and the medium-scalemethod instead.At this time, you must use the medium-scale algorithm to solve equalityconstrained problems.Medium-Scale OptimizationIf the matrices C, A, orAeq are sparse, and the problem formulationis not solvable using the large-scale method, lsqlin warns that thematrices are converted to full.Warning: This problem formulation not yet availablefor sparse matrices.Converting to full to solve.When a problem is infeasible, lsqlin gives a warning:Warning: The constraints are overly stringent;there is no feasible solution.In this case, lsqlin produces a result that minimizes the worst caseconstraint violation.When the equality constraints are inconsistent, lsqlin givesWarning: The equality constraints are overly stringent;there is no feasible solution.LimitationsAt this time, the only levels of display, using the Display option inoptions, are'off' and 'final'; iterative output using 'iter' is notavailable.8-164
