What Is Optimization Toolbox?

linprogx = linprog(f,A,b,Aeq,beq,lb,ub,x0,options) minimizes with theoptimization options specified in the structure options. Useoptimsetto set these options.[x,fval] = linprog(...) returns the value of the objective functionfun at the solution x: fval = f'*x.[x,lambda,exitflag] = linprog(...) returns a value exitflagthat describes the exit condition.[x,lambda,exitflag,output] = linprog(...) returns a structureoutput that contains information about the optimization.[x,fval,exitflag,output,lambda] = linprog(...) 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 linprog. “Options” on page 8-133 provides thefunction-specific details for the options values.“Function Arguments” on page 6-2 contains general descriptions ofarguments returned by linprog. This section provides function-specificdetails for exitflag, lambda, andoutput:exitflagInteger identifying the reason the algorithmterminated. The following lists the values ofexitflag and the corresponding reasons thealgorithm terminated.1 Function converged to a solution x.0 Number of iterations exceededoptions.MaxIter.8-132
