WebOct 19, 2024 · You have essentially the correct approach. Your ‘f’ function needs to easily accommodate two arguments in order to do the surface plot. The marker plots below the surface plot, so I made it a bit more visible, and I eliminated the edges and increased the transparency of the surface in order to see it. WebApr 6, 2014 · 1 Answer Sorted by: 2 Nonlinear optimization is a very difficult problem, so no method is guaranteed to work for every case. For your case, you can solve x (2) analytically from x (1). So you can make it into an unconstrained optimization problem. func_cstr = @ (x) func (x, 4/x); fminsearch (func_cstr, initial_x1)

Webfminsearch finds the minimum of a scalar function of several variables, starting at an initial estimate. This is generally referred to as unconstrained nonlinear optimization. x = fminsearch(fun,x0) starts at the point x0 and finds a local minimum x of the function described in fun. x0 can be a scalar, vector, or matrix. WebAug 29, 2024 · You do not define them. You define the objective function I already showed, and you give the objective function to an optimizer. At each stage, the optimizer will supply specific n and m values, and your objective function will evaluate how good those particular values are, and the optimizer will figure out the best combination.
