What Is Optimization Toolbox?

quadprog[x,fval] = quadprog(...) returns the value of the objective functionat x:fval = 0.5*x'*H*x + f'*x.[x,fval,exitflag] = quadprog(...) returns a value exitflag thatdescribes the exit condition of quadprog.[x,fval,exitflag,output] = quadprog(...) returns a structureoutput that contains information about the optimization.[x,fval,exitflag,output,lambda] = quadprog(...) returns astructure lambda whose fields contain the Lagrange multipliers at thesolution x.Note If the specified input bounds for a problem are inconsistent, theoutput x is x0 and the output fval is [].InputArgumentsOutputArguments“Function Arguments” on page 6-2 contains general descriptions ofarguments passed into quadprog. “Options” on page 8-194 providesfunction-specific details for the options values.“Function Arguments” on page 6-2 contains general descriptionsof arguments returned by quadprog. This section providesfunction-specific details for exitflag, lambda, andoutput:exitflagInteger identifying the reasonthealgorithmterminated. The following lists the values ofexitflag and the corresponding reasons thealgorithm terminated:1 Function converged to asolution x.8-192
