How to check optimized values after stopping the program midway?

I am using lsqnonlin (Levenberg-Marquardt algorithm) code to optimize 4 variables as can be seen in attached file. Many times I wish to stop my program mid way to check optimized values resulted from last iteration.Once I press ctrl+c in coomand window, program stops but does not give optimized value. I know that stopping and checking results mid way is possible using optimization toolbox. but I wish to use code and then check the solution mid way. Can anyone help.

You can use a plot function to monitor your optimization. You can write a custom plot function that writes data to a variable at every iteration so you don't lose anything if you stop it midway. An output function can do this, too, and that link shows an example of keeping a history.
