r=amount;

tnb=0;

i=1;

while r~=0

nb(i)=floor(r./bill(i));

tnb=tnb + nb(i);

r=rem(r ,bill(i));

    if nb(i) >= 1 
       fprintf('%.0f of resistors %.0f \n' ,nb(i) ,bill(i))
    end

    i=i+1;
end
fprintf(' %.0f resistors in total \n' ,tnb)

How do i make it so it stops at the ideal combination? eg, if i type in 18 it will return 18 with 1 resistor in total, but if i type 20, i want it to stop at 18 as well but the code seems to want to keep going but it becomes out of bounds, anyway of stopping this? :D

Try this:

while r~=0 && i <= length(bill)

and also see this.
