Results from Genetic Algorithm are lost

I was using GA to find the global optima for an optimization problem. I used the hybrid function "fmincon" in the combination with GA so I put ('hybridfcn',@fmincon). The GA ran for few days and I was able to see the average error was going down (through the plot) it reached to a very promising point (f_value) and converged, so it automatically started using the final results as the initial guess for "fmincon" that I got an error massage (saying there is something wrong with inputs) and now when I type x to see the final results from GA it says undefined x. How can I retrieve the last x that GA converged to (Forget about fmincon I do not need it anymore).

You cannot. The data is gone now.

You should debug your code with a much shorter run.

Ideally you should write long code so that it periodically saves its state so that you can resume from there if a problem occurs.

In practice: before doing the run, give the command

dbstop if error

then if a problem occurs you will be put into the debugger with access to the workspace variables.
