I did … Webfmincon calculates an approximate set of Lagrange multipliers λi , and packages them in a structure. To include the Hessian, use the following function. function hess = quadhess (x,lambda,Q,H) hess = Q; jj = length (H); % jj is the number of inequality constraints for i = 1:jj hess = hess + lambda.ineqnonlin (i)*H {i}; end Solution
WebBounded Least-Squares and Trust-Region-Reflective Solvers. For least-squares solvers and trust-region-reflective algorithms, in problems with bounds alone, the first-order optimality measure is the maximum over i of v i *g i . Here g i is the ith component of the gradient, x is the current point, and .
