MATLAB: While loop iteration in matlab

Question

If I am have this code as example

 while(A>0.0000001);
 statment
 .
 .
 .
 end

How can save value of A to each iteration until reach 0.0000001?

I mean there is (A) at first iteration, (A) at second iteration,and so on

Answer 1

K = 1;
A(K) = .... some initial value ...
while( A(K) >0.0000001)
  statment
  .
  .
  .
  K = K + 1;
  A(K) = new value for A
end
