WebThe real equivalent to fminsearch for gradient-aware optimization is fminunc, which implements Newton's method and some extensions of it. All nonlinear optimization requires a decent starting point (unless it's convex). Local minima can always be a problem, but usually some reasonable efforts to compute a starting guess will fix that issue. Webfminunc 采用拟牛顿法(QN),是一种使用导数的算法。参见. 拟牛顿法 分析与推导. fminsearch 采用Nelder-Mead单纯形法,是一种直接搜索法。参考. 单纯形法、Simplex Method WebAug 7, 2024 · 对于非线性规划问题,目前还没有一种适用于一般情况的求解方法,各种方法都有各自特定的应用范围。一、无约束非线性规划的求解1、基于求解器求解在MatLab工具箱中,用于求解无约束极小值问题的函数有 fminunc 和 fminsearch (局部最优化算法),fminunc(采用拟 literature business
