MATLAB: How to model the objective function for optimization? in quadprog non-linear optimizationoptimizationquadprogquadratic programming x(1)+x(2)+x(3)+x(4)+x(5)+x(6)+x(7)+0.3*x(5)^2+0.3*x(6)^2+0.3*x(7)^2 If someone know please help. Thank You. Best Answer As the function reference page for quadprog states, the objective function in terms of the matrices H and f is1/2*x'*H*x + f'*xYou have a 7-dimensional x. So f = ones(7,1) for the first seven terms of your sum. Then you have three terms for quadratic terms. TakeH = spalloc(7,7,3); % Sparse 7-by-7 array with 3 nonzero entriesH(5,5) = 2*0.3;H(6,6) = 2*0.3;H(7,7) = 2*0.3;The reason you multiply those entries by 2 is because of the 1/2 in the definition of the quadprog objective function.Alan WeissMATLAB mathematical toolbox documentation Related SolutionsMATLAB: How to find the optimal values of inputs when outputs have constraints in optimization Use fmincon.
