Im trying to do calculations with x with different b, so for example the first calculation is with b = 1/5 0 0 0 0 0 0 0 ....
then the next calculation with x will be with 1/5 now being in second index like b = 0 1/5 0 0 0 0 0 ......
till the last calculation b = 0 0 0 0 0 0.......1/5.
b = zeros(size(A,1),1);
>> b(1) = 1/5;
>> for i=1:size(A,1);
x = A\b;
b(i+1) = b(i);
b(i-1) = 0;
end

N = size(A,1);
for k = 1:N
b = zeros(1,N);
b(k) = 1/5;
x = A\b;
end
