Matlab Optimisation toolbox (Score Constaint)

Greeting all,

I have a long matlab code, but essentially what I have is a TARGETVALUE and ACTUALVALUE variables, I am trying to optimise the the function so that the difference between those is 0. However, my optimiser keeps omptimising the problem to the point where the difference is negative.

Is there a way to limit the "Score" to 0 and restrict it from going to negatives?

Any help would be much appreciated.

Instead of minimizing TARGETVALUE - ACTUALVALUE , instead minimize either abs(TARGETVALUE - ACTUALVALUE) or (TARGETVALUE - ACTUALVALUE)^2.
