Webfmincon uses a sequential quadratic programming (SQP) method. In this method, the function solves a quadratic programming (QP) subproblem at each iteration. fmincon updates an estimate of the Hessian of the Lagrangian at each iteration using the BFGS formula (see fminunc and references [7] and [8] ). http://www.ece.northwestern.edu/IT/local-apps/matlabhelp/toolbox/optim/fmincon.html

Webfmincon has five algorithm options: 'interior-point' (default) 'trust-region-reflective' 'sqp' 'sqp-legacy' 'active-set' Use optimoptions to set the Algorithm option at the command line. Recommendations Use the 'interior-point' algorithm first. For help if the minimization fails, see When the Solver Fails or When the Solver Might Have Succeeded.
