Mead Fminsearch uses Nelder Mead Fminsearch finds minimum of a function of several variables starting from an initial value Unconstraint nonlinear optimization method meaning we cannot give upper or lower bounds for parameters. Most local search algorithms are based on derivatives to guide the search.. For differentiable function it has been shown that even if you need to calculate derivatives by finite differences, derivative-based algorithms are better than ones that do not use derivatives..
