Matlab中未定义的函数或变量"optimoptions" [英] Undefined function or variable 'optimoptions' in Matlab

问题描述

我在文档中使用它:

options = optimoptions('fminunc','GradObj','on','Hessian','on');

出于某种原因，我收到此错误:

and for some reason I get this error:

Undefined function 'optimoptions' for input arguments of type 'char'.

我不确定是什么问题.当我在Matlab中键入optimoptions时 它说:

I am not sure what is the problem. Also when I type optimoptions in Matlab it says:

Undefined function or variable 'optimoptions'.

谢谢

推荐答案

函数optimoptions是MATLAB R2013a中新引入的.您可能正在使用MATLAB的旧版本.如果是这样，请使用optimset而不是optimoptions.

The function optimoptions was newly introduced in MATLAB R2013a. It might be the case that you are using an older version of MATLAB. If so use optimset instead of optimoptions.
