WebMedium-Scale Optimization. fmincon uses a Sequential Quadratic Programming (SQP) method. In this method, a Quadratic Programming (QP) subproblem is solved at each iteration. An estimate of the Hessian of the Lagrangian is updated at each iteration using the BFGS formula (see fminunc, references , ). WebOptimization Toolbox 提供了多个函数，这些函数可在满足约束的同时求出可最小化或最大化目标的参数。该工具箱包含适用于下列各项的求解器：线性规划 (LP)、混合整数线性规划 (MILP)、二次规划 (QP)、二阶锥规划 (SOCP)、非线性规划 (NLP)、约束线性最小二乘、非线性最小二乘和非线性方程。
