I have a vector A = [0,0,0] & B = [4,2,1]

i = 1:length(B)  -->> I am not sure about this part
while (A(i) <= B(i))
A(i) = A(i) + 1;
end

I need to perform this while loop according to B values. To give you a clear picture; first while loop should consider B(1) which is 4. Therefore while loop should be carried out 4 times. here the output will of A will change to A = [4,0,0]. Once done, B(2)--> which is 2. So while loop should be done 2 times and o/p now will be A = [4,2,0] and then B(3) ---> which is 1. So the Final output of A will be [4,2,1] instead of [0,0,0].

to make your code work you just need to add 'for'

for it = 1:length(B) 
while (A(it) <= B(it))
A(it) = A(it) + 1;
end
end

However it might be possible to avoid using multiple loops, depending on what you want to do. Right now A=B would do the trick but i assume thats not what you actually want.
