WebAug 11, 2015 · We also provide this as an additional parameter to fminsearch to let the function know we are providing some changes to the default parameters for the optimization routine. By doing this, we now get: >> [a,b,c] = SolveForParameters (1:10, 11:20, 21:30) a = 7.4210e-07 b = 325.4225 c = -2.0911. Share. Improve this answer. WebMay 6, 2016 · You have to combine your independent variables into a matrix, then refer to the matrix columns within your regression function as the individual independent variables. This will work with fminsearch, nlinfit, and lsqcurvefit. (I don’t have the Curve Fitting Toolbox, so I can’t comment on it.)

WebJun 18, 2012 · I dont know how many data sets you have, but the problem is that fminsearch is not well suited for optimizing for more than a couple of variables, so you problably need the optimization toolbox (fminunc) to solve this in a reasonable amount of time... or you can write your own procedure (easier than it seems ) 0 Comments Sign in … 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.
