ker - what type of iteration process are you interested in? while loops, inner for loops, or something else? Please be more specific as your question is much too general.

xrange = 0:24;
a= [ 1 5 15 18 10 9 6 4 12 11];
b = (a+2*a); %function
b;
best = min (b);
N=100;
v = 0;
x = a;
for i = 1:N
v = velocity(i);
velocity(i+1) = 0.9*velocity(i) + 2*(0.5)*(b-a)+2*(0.5)*(best - a);
xnew = a + velocity(i+1);
d = xnew + 2*xnew;
d;
b1 = sum (b);
d1 = sum(d);
if d1>b1;
result = a;
else if b1>=d1;
result = xnew;
end
end
this is the example of my code, how do i replace the new velocity value into the velocity equation?
