Hello Matlab Community,
I have a questio about the Matlab Global Optimization features.
I would like to get, at the end of the optimization, all the solutions, also the ones with negative exit flags and respective parameters values.
I use the following syntax
[x,fval,exitflag,output,solutions] = run(...)
but I only get, in [solutions], the local minima with a positive exit flag, and I would like to check all the others as well.
Is there a way to accomplish what I need, that I have missed?
Many thanks and best regards.

Sorry, no, GlobalSearch and MultiStart do not consider the points corresponding to negative local exit flags as being solutions, and so do not store them in the returned GlobalOptimSolution object.
Why do you want these points?

Certainly, use your output function to save the point.

You can make your solutions as global variables that get saved into a matrix
