What Is Optimization Toolbox?

lsqlinPrecondBandWidthUpper bandwidth of preconditioner for PCG. Bydefault, diagonal preconditioning is used (upperbandwidth of 0). For some problems, increasing thebandwidth reduces the number of PCG iterations.Setting PrecondBandWidth to 'Inf' uses adirect factorization (Cholesky) rather than theconjugate gradients (CG). The direct factorizationis computationally more expensive than CG, butproduces a better quality step towards the solution.TolFunTolPCGTermination tolerance on the function value.Termination tolerance on the PCG iteration.ExamplesFind the least-squares solution to the overdetermined systemsubject to and .First, enter the coefficient matrices and the lower and upper bounds.C = [0.9501 0.7620 0.6153 0.40570.2311 0.4564 0.7919 0.93540.6068 0.0185 0.9218 0.91690.4859 0.8214 0.7382 0.41020.8912 0.4447 0.1762 0.8936];d = [0.05780.35280.81310.00980.1388];A =[0.2027 0.2721 0.7467 0.46590.1987 0.1988 0.4450 0.41860.6037 0.0152 0.9318 0.8462];b =[0.52510.20268-161
