optimization with one exogenous symbolic variable and three endogenous variables

I am wondering that is there any approach to solve the target function as following by choosing x(1), x(2), x(3). m is an exogenous symbolic variable.

Any help is appreciated.

If you have Optimization toolbox, then you can employ a few available tools (GA, patternsearch, Paretosearch) for your exercise. See this help doc:

Hello, Thank you for your quick reply. Optimization toolbox can solve the common optimization problem, however, my objective function has an exongerous variable, m. When I use GA as in the example, it results in error code. Do you know how to solve this? Many thanks for any help.
