What Is Optimization Toolbox?

lsqlinPurposeEquationSolve constrained linear least-squares problemsSolves least squares curve fitting problems of the formwhere C, A, andAeq are matrices and d, b, beq, lb, ub, andx are vectors.SyntaxDescriptionx = lsqlin(C,d,A,b)x = lsqlin(C,d,A,b,Aeq,beq)x = lsqlin(C,d,A,b,Aeq,beq,lb,ub)x = lsqlin(C,d,A,b,Aeq,beq,lb,ub,x0)x = lsqlin(C,d,A,b,Aeq,beq,lb,ub,x0,options)[x,resnorm] = lsqlin(...)[x,resnorm,residual] = lsqlin(...)[x,resnorm,residual,exitflag] = lsqlin(...)[x,resnorm,residual,exitflag,output] = lsqlin(...)[x,resnorm,residual,exitflag,output,lambda] = lsqlin(...)x = lsqlin(C,d,A,b) solves the linear system C*x=d in theleast-squares sense subject to A*x
