Stopping criteria for fminsearch in Matlab. Ask Question Asked 6 years ago. Modified 5 years, 4 months ago. Viewed 2k times 0 I am using fminsearch to fit parameters for a system of DEs to observed data. I am not expecting to get a great fit. fminsearch pretty quickly finds what appears to be an acceptable min for the objective function, but ... fminsearch 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.

First methodThe fminsearch function is similar to fminbnd except that it handles functions of many variables. Specify a starting vector x 0 rather than a starting interval. fminsearch attempts to return a vector x that is a local minimizer of the mathematical function near this starting vector.3. You can't tell fminsearch to consider only integers. The algorithm it uses is not suitable for discrete optimization, which in general is much harder than continuous optimization. If there are only relatively few plausible values for your integer parameter (s), you could just loop over them all, but that might be too expensive.fsolve is a function that evaluates another function. You'd need to find the gradient w/ respect to your variables. Then you'd need to take an optimization step. Presumably, you'd use a self-written, non compiled optimization algorithm for this.
