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 then does not stop. It's running for a really long time, and I cannot figure out why. I am using the options

WebNov 22, 2024 · I am using Matlab fminsearch to minimize a equation with two variables sum ( (interval-5).^2, 2)*factor The interval is a vector contains 5 values. They can be only picked sequentially from value 1 to 30 with step size is 1. The factor is a value from 0.1 to 0.9. The code is below. I think the interval values are correct but factor value is wrong.
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 = … WebNov 23, 2024 · It's easiest with the entire time-vector of all states. You could create a global variable, to which you add the current state at every iteration in the 'OutputFnc'. After fminsearch converged, you call the global variable in the base workspace and plot it as a simple line plot – max Nov 23, 2024 at 7:03
