Linear Programming Using Matlabв® -

Linear programming problems with two variables can be visualized by plotting the feasible region defined by the constraints. 5. Advanced Tips

Before coding, you must express your problem in the standard mathematical form used by MATLAB: minxfTxmin over x of bold f to the cap T-th power bold x Linear Inequalities: Linear Equalities: Boundaries: 2. The linprog Syntax The most common way to call the solver is: [x, fval] = linprog(f, A, b, Aeq, beq, lb, ub) Use code with caution. Copied to clipboard f : Vector of coefficients for the objective function. x : The solution (optimal values for your variables). fval : The value of the objective function at the solution. 3. Practical Example Suppose you want to maximize (which is equivalent to minimizing Constraints: MATLAB Implementation:

If your variables must be integers, use the intlinprog function instead.

% Define objective function (minimization) f = [-3; -2]; % Inequality constraints (A*x <= b) A = [2, 1; 1, 1]; b = [10; 8]; % Lower bounds (x >= 0) lb = [0; 0]; % Solve [x, fval] = linprog(f, A, b, [], [], lb); fprintf('Optimal x1: %.2f\n', x(1)); fprintf('Optimal x2: %.2f\n', x(2)); fprintf('Maximized Value: %.2f\n', -fval); Use code with caution.

You can specify the algorithm using optimoptions . The default is often 'dual-simplex', which is robust for most standard problems.
