For each fmincon it overwrites the previous values, meaning at the end there is only 1 set of values when there should be 100. The code is running 100 times and displays all sets of values but not storing all sets. How do I resolve this?
Your code is inefficient in that you define many things inside the loop that should be assigned outside the loop. Using Walter's...
