I wrote a code using diff function to model some parameters. Now, I need to adjust some parameters with GA Matlab Toolbox. The parameters that I am aiming to optimize, have been used in the diff function, as well.
Is that work? I mean, can I optimize parameters that is used in the diff function? If yes, useing diff may decrease the spead of calculation? Is it recommneded to apply analytican deriviative instead of diff approximation?
