What Is Optimization Toolbox?

lsqlinx = lsqlin(C,d,A,b,Aeq,beq,lb,ub,x0,options) minimizes withthe optimization options specified in the structure options. Useoptimset to set these options.[x,resnorm] = lsqlin(...) returns the value of the squared 2-normof the residual, norm(C*x-d)^2.[x,resnorm,residual] = lsqlin(...) returns the residual C*x-d.[x,resnorm,residual,exitflag] = lsqlin(...) returns a valueexitflag that describes the exit condition.[x,resnorm,residual,exitflag,output] = lsqlin(...) returns astructure output that contains information about the optimization.[x,resnorm,residual,exitflag,output,lambda] = lsqlin(...)returns a structure lambda whose fields contain the Lagrangemultipliers at the solution x.Note If the specified input bounds for a problem are inconsistent, theoutput x is x0 and the outputs resnorm and residual are [].InputArgumentsOutputArguments“Function Arguments” on page 6-2 contains general descriptions ofarguments passed into lsqlin. “Options” on page 8-158 provides theoptions values specific to lsqlin.“Function Arguments” on page 6-2 contains general descriptions ofarguments returned by lsqlin. 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 solutionx.8-156
