5 Optimization ToolX1 and X2 for which the function differs in sign. When this is selected, thealgorithm assumes the objective function values at X1 and X2. An erroroccurs if this is not true. Alternatively, you can select Let algorithm findinterval containing X and enter the scalar X valuetohavethealgorithmattempt to find a zero of the objective function near X.Function EquivalentFor the function that corresponds to this solver and more information on theproblem definition, see the fzero function.linprog Problem SetupAlgorithmSpecify whether you want to use large or medium scale. Within medium scalethere are two option choices: the simplex or the active set algorithm. For moreinformation on the routines Optimization Toolbox uses for these choices, see“Medium- and Large-Scale Algorithms” on page 2-7.5-20
Defining the ProblemFunction to Minimizef (required) is a vector containing the coefficients of the linear function youwant to minimize.ConstraintsYou must specify at least one constraint to run the solver.Linear inequalities of the form A*x ≤ b are specified by the matrix A andthe vector b.Linear equalities of the form Aeq*x = beq are specified by the matrix Aeqand the vector beq.Bounds are lower and upper bounds on the variables, specified as vectors.Start PointStart point is the initial point (vector) for the algorithm. You can selectLet algorithm choose point or set your own start point. You can onlysetyourownstartpointwiththemedium-scaleactivesetalgorithm. Thedefault large-scale algorithm and the simplex algorithm ignore the start pointentered.Function EquivalentFor the function that corresponds to this solver and more information on theproblem definition, see the linprog function.5-21
