Question

hi, i need to store the best cost value for all iteration.

my code is,

while(i<maxitr)                       
     i=i+1;                     
     // function calling
    if best_cost < best_cost1 && best_cost < best_cost2
        best_cost= best_cost
    elseif best_cost1 < best_cost && best_cost1 < best_cost2
        best_cost= best_cost1
    else
        best_cost= best_cost2
    end

THANKS IN ADVANCE

Answer 1

After the if/elseif/else, put in

best_costs(i) = best_cost;
